End-to-End Migration Project Example

End-to-End Migration Project Example

A useful Toolkit is not six completed tabs. It is a connected project-control system where each task, risk, validation result, redirect, and decision answers a different question while still pointing back to the same project outcome.

This worked example follows one illustrative replatforming project from preparation through launch planning. The values are examples, not product defaults. For a live project, confirm the actual migration path, purchased service, Entity Points Plan, Add-ons, Customization, service expiry, and supported data from the Next-Cart account and the relevant Documentation.

Follow the walkthrough in the example workbook

Keep the example workbook open while reading this page. The workbook contains the populated Project Overview, Project Plan, Risk Register, Validation, Redirects, and Decisions & Sign-off records referenced throughout the walkthrough, so you can inspect how the relationships work in the actual template.

Example project at a glance

The scenario is a retail replatforming project moving from Magento 2 to Shopify under Custom Service. The project uses Data Filter and Advanced Data Mapping and includes approved non-standard handling for legacy loyalty identifiers.

The non-standard loyalty-identifier handling belongs to approved Custom Service scope. Purchased Add-ons and Customization are planned for paid migration; neither operates inside the Demo.

At the example review point, the project is in Demo validation. Preparation, scope, acceptance criteria, configuration, and the Demo run are complete. Validation is still open because one URL test failed and a separate mapping approval is still pending.

Project control	Example value	Why it matters
Project	Example Retail Replatforming	Gives the workbook one identifiable project boundary.
Migration Path	Magento 2 -> Shopify	Anchors connection, supported-data, configuration, and validation decisions to one direction.
Migration Service	Custom Service	Establishes the purchased execution model for the example.
Purchased Add-ons	Data Filter; Advanced Data Mapping	Identifies configuration capabilities that must appear in scope, review, and validation planning.
Approved Customization	Non-standard handling for legacy loyalty identifiers	Keeps approved custom scope visible before configuration and acceptance decisions are made.
Project Owner	Customer Project Lead	Owns coordination and project decisions.
Launch Approver	Executive Sponsor	Owns final authorization where the project requires executive approval.
Evidence Repository	Secure project workspace	Keeps detailed evidence outside the workbook while preserving controlled references.
As of Date	August 10, 2026	Makes overdue-task and readiness calculations meaningful for the review.
Project Status	Demo validation	Tells reviewers which project stage the evidence represents.

Use Migrations to confirm the live purchased-service details before filling Project Overview. Use Supported Data Types and Processing Order when the project needs a supported-data reference for the exact migration path.

Do not copy commercial example values into a live project

The example demonstrates project-control behavior, not plan availability, pricing, capacity, or platform support. Record only the values verified for the actual purchased migration.

1. Establish the project baseline before creating tasks

Start in Project Overview. The baseline should answer three questions before the team starts adding work:

1. Which purchased migration is this workbook controlling?
2. Who owns execution, review, and launch authorization?
3. Which dates and evidence locations define the project state?

In this example, the migration path, service, Add-ons, Customization, owners, milestone dates, As of Date, and project status are established first. That baseline prevents later task and validation rows from drifting into a different environment or commercial scope.

Two fields deserve special discipline in a live project:

• Supported Data Reference should point to the approved migration-path reference rather than a guessed URL.
• Service Expiry should be copied from the purchased migration details rather than inferred from a planning date.

If either value is not confirmed, leave it unresolved and obtain the correct evidence before using the Overview as the authoritative project summary.

2. Turn the migration lifecycle into accountable Project Plan outcomes

The example Project Plan does not list generic activities such as “check migration.” Each row describes an outcome, an acceptance condition, an owner, an approver, a gate, dependencies, and evidence.

Task ID	Project outcome	Gate	Example state	Key relationships
PREP-01	Confirm Source Platform and Target Platform access	Access ready	Completed	Risk R-004
SCOPE-01	Approve migration scope and intentional exclusions	Scope approval	Completed	PREP-01, R-003, VAL-001, VAL-002
AC-01	Approve acceptance criteria and risk-based validation samples	Acceptance criteria approved	Completed	SCOPE-01, R-001, R-002, VAL-001 to VAL-003
CFG-01	Configure the supported Demo data, reduced Additional Options, and displayed Attribute Mapping	Demo configuration ready	Completed	AC-01, R-001, R-003, VAL-001, VAL-002
DEMO-01	Run Demo Migration	Demo results available	Completed	CFG-01, Demo risks and validation items
VALGATE-01	Validate Demo Migration results	Demo validation decision	In progress, blocking	DEMO-01, R-001 to R-003, VAL-001 to VAL-004
DEC-01	Approve the separate paid configuration, including applicable purchased Add-ons and approved Customization	Full Migration configuration approval	Not started, blocking	VALGATE-01, R-001, R-002, VAL-002, VAL-004
FULL-01	Run Full Migration using the approved configuration	Full Migration complete	Not started	DEC-01, R-005, later Full Migration validation
FULLVAL-01	Validate Full Migration results	Full Migration sign-off	Not started	FULL-01, data and launch risks, Full Migration validation
LAUNCH-01	Complete launch-readiness and redirect checks	Launch readiness decision	Not started	FULLVAL-01, R-002, R-004, redirect and launch validation
GO-01	Record the go-live decision	Go-live	Not started	LAUNCH-01, launch risks and validation
MON-01	Monitor target-store behavior after launch	Post-launch closure	Not started	GO-01, post-launch risks and validation

This sequence creates a practical control chain:

access -> scope -> acceptance criteria -> Demo configuration -> Demo -> Demo validation -> paid configuration approval -> Full Migration -> Full validation -> launch readiness -> go-live -> monitoring

The operational procedures still live in the Documentation. For example, use Demo Migration walkthrough to perform the Demo and Run a Full Migration to execute the Full Migration. The Project Plan records whether the project-specific outcome has been met and what evidence proves it.

Use unambiguous ID namespaces

Keep task, risk, validation, redirect, and decision identifiers visually distinct. A production workbook is easier to audit when project tasks use stable workstream prefixes and R-*, VAL-*, RED-*, and DEC-* are reserved for their corresponding registers.

3. Record uncertainty before it becomes a defect

The Risk Register turns future uncertainty into an owned control. The example contains five risks that cover different parts of the migration rather than treating every problem as a data defect.

Risk	Concern	Inherent exposure	Main control	Residual exposure	Connected work
R-001	Complex Product variants could map into incorrect purchasable combinations	4 x 5 = 20, Critical	Put the highest-complexity Products into Demo validation	2 x 4 = 8, Moderate	VALGATE-01, Product validation
R-002	Priority source URLs may not reach approved target destinations	3 x 5 = 15, High	Build and test a priority redirect plan before go-live	2 x 5 = 10, High	LAUNCH-01, VAL-004, redirect work
R-003	Business-critical source data may sit outside standard supported fields	3 x 4 = 12, High	Define the field, dependencies, target use, and required Custom Service assessment	2 x 3 = 6, Moderate	SCOPE-01, Customization and validation
R-004	Checkout, tax, payment, fulfillment, or target configuration may fail even when migrated data is correct	2 x 5 = 10, High	Complete target-store launch checks and a smoke test	1 x 5 = 5, Moderate	LAUNCH-01, GO-01
R-005	A fresh migration decision could conflict with protected target records	2 x 5 = 10, High	Inventory protected target data before destructive or fresh-result actions	1 x 5 = 5, Moderate	FULL-01

The important relationship is not the score alone. Each material risk points to a task or validation activity that can prove whether the control works. Once an uncertainty becomes an observed failure, manage the actual finding in the appropriate task, Validation row, Redirect row, or decision instead of rewriting the risk statement as a defect log.

Use Risk Register for the scoring and treatment rules.

4. Create validation rows before the project reaches the gate

The example demonstrates why validation planning should happen before execution. By the time Demo results arrive, the team already knows which records matter, what a pass condition means, who will validate them, and which risks the checks address.

Validation ID	Activity / area	Example result at the review point	What happens next
VAL-001	Demo Migration / Products	Pass	Keep evidence; no corrective decision is required for the observed result.
VAL-002	Demo Migration / Categories	Pass with accepted limitations	Link decision DEC-001 because the target structure differs from the source but preserves approved business meaning.
VAL-003	Demo Migration / Customers	Pass	Keep masked evidence and proceed.
VAL-004	Demo Migration / URLs and redirects	Fail, High, blocking	Assign corrective ownership, connect RED-001, keep DEC-004 open, and retest before launch approval.
VAL-005	Full Migration / Orders	Not tested	Keep the row planned for the Full Migration validation gate.
VAL-006	Launch readiness / Checkout	Not tested	Keep the row planned for the launch smoke test.

The Project Plan also anticipates later validation IDs for Full Migration, launch readiness, and post-launch monitoring. A reliable production practice is to create the Validation row as soon as an ID is referenced by another sheet, even when the activity is still future work. Set the result to Not tested and record the objective, owner, and planned date. This prevents a project dependency from pointing to an undefined ID.

IDs create human traceability. The workbook does not automatically prove that every referenced ID exists, so the project review should include a quick cross-sheet ID check.

Use Define Acceptance Criteria to establish the sample and pass conditions, then use Validation evidence to manage the project record.

5. Use different downstream paths for Pass, accepted limitation, and Fail

The example contains three different Demo outcomes. Treating them differently is one of the most important uses of the Toolkit.

Pass: VAL-001

The Product sample confirms the approved option labels, purchasable combinations, price, SKU, and media associations. The row records Pass, the evidence location, and no retest requirement.

A Pass closes the validation item when the evidence is complete. It does not need a separate decision simply to restate that the check succeeded.

Pass with accepted limitations: VAL-002 -> DEC-001

The Categories sample is flatter in the target platform than in the source hierarchy, but approved Product membership, navigation, and discoverability are preserved. The validation row records Pass with accepted limitations and links to DEC-001.

DEC-001 then records:

• what difference is being accepted;
• why it is acceptable;
• the approving authority;
• the evidence location;
• the monitoring condition after launch;
• that the limitation does not block launch.

This keeps the validation finding and business authorization separate without losing the connection between them.

Fail: VAL-004 -> RED-001 -> DEC-004

The priority source path /old-running-shoes is expected to reach /collections/running-shoes, but the target staging environment returns 404.

The validation row therefore records Fail, High severity, Blocking? = Yes, corrective ownership, retest requirement, and the related decision.

The URL-specific implementation evidence then moves to RED-001, while the project authorization remains in DEC-004. Risk R-002 stays visible because the business exposure has not yet been reduced to an acceptable state.

Use Review Demo Results for the immediate post-Demo decision and Validate Demo Results for the detailed validation procedure.

6. Use Redirects for URL-level evidence, not general issue tracking

The Redirects sheet in the example demonstrates four different URL outcomes.

Redirect ID	Pattern	Test evidence	Readiness meaning
RED-001	Required redirect is not implemented and the source path returns 404	Test Result = Fail	Blocked until corrected and retested.
RED-002	Product URL is preserved	HTTP 200, final destination is the intended Product path	Ready because no redirect is required and the path is usable.
RED-003	Source blog path moves to a target Page	HTTP 301, correct final destination, no chain or loop	Ready after implementation and test pass.
RED-004	Obsolete campaign URL is intentionally retired	No redirect, accepted retirement linked to DEC-003	Not required because the no-redirect outcome is deliberate and authorized.

The four rows show why “redirect present” is not the acceptance criterion. The project needs the intended URL behavior to be explicit and tested. A preserved URL can be correct, a 301 can be correct, and an intentionally retired URL can be correct when the decision is authorized and documented.

For a material URL, keep the relationship bidirectional when practical. Once a Decision ID exists, add it to the Redirect row as well as linking the Redirect ID from the decision. This allows either register to reconstruct the same approval chain.

Use Redirects and URL Continuity for the workbook fields and Validate Content, URLs, and Redirects for the validation procedure.

7. Use Decisions & Sign-off only when authorization is required

The Decisions & Sign-off sheet does not duplicate Project Plan status. It records who authorized a scope choice, accepted limitation, exclusion, mapping decision, launch condition, or other project decision.

Decision ID	Decision	Outcome	Launch blocking?	Why the record exists
DEC-001	Accept flatter target collection structure	Approved with limitations	No	Preserves an accepted target-model difference and its monitoring condition.
DEC-002	Approve corrected Product option and variant mapping for Full Migration	Pending	Yes	Prevents Full Migration approval from moving forward before the required mapping evidence is complete.
DEC-003	Retire an obsolete campaign URL without redirect	Approved	No	Makes the intentional exclusion auditable instead of leaving an unexplained 404.
DEC-004	Approve or defer go-live after the priority redirect defect is retested	Pending	Yes	Keeps launch authorization blocked until the priority URL has acceptable evidence.

A decision row should answer who authorized what, based on which evidence, under which conditions, and whether the project may proceed. That is different from the task row, which answers who must complete the work and whether the work is finished.

Use Decisions and Sign-off together with Define Sign-off Criteria.

8. Read the Overview as a calculated investigation map

At the example review point on August 10, 2026, the underlying rows produce the following project picture:

Overview indicator	Example state	Interpretation
Task completion	5 of 12, 41.7%	Preparation through the Demo run is complete; later gates remain open.
Open task blockers	2	Demo validation and the configuration-approval task are explicitly blocking progression.
Residual High / Critical risks	1	R-002 remains High after mitigation.
Validation failures	1	VAL-004 is the open failed validation item.
Redirect blockers	1	RED-001 is blocked.
Open launch decisions	2	DEC-002 and DEC-004 are launch-blocking and not yet approved.
Validation completion	4 of 6, 66.7%	Four entered validation rows have terminal results; two remain Not tested.
Overall readiness	Not ready	At least one readiness-blocking signal remains.

The value of this summary is diagnostic. A reviewer can move from the red signal to the exact working record instead of debating a generic percentage.

For example:

• Validation failures = 1 leads to VAL-004.
• VAL-004 points to R-002, RED-001, and DEC-004.
• Open launch decisions = 2 leads to DEC-002 and DEC-004.
• DEC-002 points back to Product mapping evidence and the Full Migration approval gate.

The Overview does not resolve those items. It tells the team where to investigate next.

Read blocker totals as signals, not unique issue counts

The Overview can count more than one blocker signal from the same underlying situation. For example, a task can be both explicitly blocking and overdue. Use the summary to open the working sheets and identify the real project issues before deciding what to do.

9. Run an efficient project review in one direction

A weekly or gate review becomes much faster when the team follows the same sequence every time.

1. Update Project Overview. Set the As of Date and Project Status.
2. Read the readiness signals. Identify non-zero blockers, failures, and open decisions.
3. Open Project Plan at the next decision gate. Filter to the work that must close before the next transition.
4. Review only the related material risks. Check the mitigation, trigger, owner, review date, and residual exposure.
5. Review validation evidence. Separate Pass, accepted limitation, Fail, and Not tested instead of treating every row as equivalent.
6. Open Redirects only for URL continuity work. Confirm implementation and retest evidence for priority routes.
7. Resolve required decisions. Do not close a task by changing its status while the approval record is still Pending.
8. Return to Project Overview. Confirm that the summary changed because the underlying evidence changed, not because a blocker was manually hidden.

This order keeps the review outcome-focused: summary -> gate -> risk -> evidence -> specialist register -> authorization -> summary.

10. Carry the same control model into Full Migration and launch

The example Project Plan already contains the later project gates even though the project has not reached them yet:

• FULL-01 for Full Migration execution;
• FULLVAL-01 for Full Migration validation;
• LAUNCH-01 for launch readiness;
• GO-01 for the go-live decision;
• MON-01 for post-launch monitoring and closure.

Before each gate begins, create the corresponding validation rows and confirm the related risks and decision criteria. Do not invent the later results in advance. Keep planned validation items at Not tested until evidence exists.

Use the Documentation in this sequence:

1. Review Migration Configuration before FULL-01.
2. Run a Full Migration to perform FULL-01.
3. Validate Full Migration Results to populate the Full Migration validation evidence.
4. Define Sign-off Criteria to close the migration-result approval gate.
5. Launch Readiness Checklist to evaluate LAUNCH-01 and the final Go or No-go decision.
6. Post-Launch Monitoring Checklist to manage MON-01 and stabilization closure.

This keeps the Toolkit synchronized with the operational workflow without turning the workbook into a duplicate instruction manual.

11. Keep one concern connected without copying it everywhere

The priority URL issue demonstrates the complete relationship model:

LAUNCH-01 task -> R-002 risk -> VAL-004 failed validation -> RED-001 URL evidence -> DEC-004 launch decision -> Project Overview blocker signals

The accepted target-model difference demonstrates a different model:

VAL-002 accepted limitation -> DEC-001 authorization -> monitoring condition -> later post-launch review

The same principle applies to Custom Service, protected target data, launch operations, and other material project concerns: put each type of information in the sheet designed to manage it, then connect the records with stable IDs.

Do not copy the complete risk statement into Validation, the complete validation finding into Decisions, or the full decision rationale into Project Plan. Shared IDs preserve traceability while each sheet keeps one clear job.

12. Apply these practices to a real project

For efficient day-to-day use:

• create a row as soon as its ID is referenced elsewhere;
• keep IDs stable after other records link to them;
• use Status for progress and Blocking? for decision impact;
• keep evidence in a secure repository and use controlled links in the workbook;
• update residual risk after mitigation or context changes;
• preserve the original failed validation finding and record retest separately;
• link accepted limitations to an explicit decision rather than hiding them in Notes;
• use Redirects only for URL continuity evidence;
• keep launch authorization in Decisions & Sign-off rather than treating Overview readiness as approval;
• review the workbook by the next project gate, not by trying to complete every cell on every sheet.

Keep sensitive data out of the example pattern

Use masked customer and Order references in validation rows. Do not store passwords, API keys, access tokens, payment details, Backup Codes, or unnecessary personal data in the Toolkit.

Next Steps

Return to Migration Project Toolkit and download the blank workbook when you are ready to start a real project. Use the example workbook as a relationship model, then establish the real project baseline in Project Overview and readiness and replace every illustrative path, owner, date, scope item, and acceptance condition with verified project information.
