Software migration and cutover
Start here
Control the moving population from extraction through cutover, then prove identities, access, documents, balances, events, and historical reports before retiring the source.
Choose the question you need to resolve
Define the source population and cutover boundary before comparing target results.
A successful import is one event; acceptance requires reconciled records, access, events, and evidence.
Temporary spreadsheets survived the first close.
Replacement controls pass live gates before duplicate writers and side records are disabled.
Retire post-cutover workaroundsCan archive dependencies be recovered from custody?
Bytes, keys, runtime, schemas, and meaning are recovered in a clean bounded environment.
Exercise dependency recoveryScheduled report subscriptions moved to the new PMS.
Definition, occurrence, audience, transport, and access agree across the cutover.
Reconcile report deliveriesThe first full close is running in the target system.
Opening, live activity, configuration, timing, and unknown differences receive separate dispositions.
Run the first-close acceptance gateRecurring charges crossed the cutover boundary.
Rules, executions, postings, and external effects agree exactly once.
Reconcile expected occurrencesSupport tickets and the defect register do not agree.
Duplicate reports still inform affected population while every ticket receives a disposition.
Build the ticket-to-defect bridgeCan archived exports still be understood?
Bytes, rendering, meaning, dependencies, and representative records are tested separately.
Test archive readabilityDid attachment permissions drift during migration?
Allowed and denied roles expose broader, narrower, broken, or unknown object-level access.
Test effective attachment accessDefects appeared after go-live.
A bounded affected population, containment, domain owner, correction release, and regression proof.
Triage the stabilization defectIs the source system ready to retire?
Operational, financial, records, technical, access, and commercial acceptance remain explicit.
Run the decommission gatesCould recurring jobs execute in both systems?
Every boundary occurrence receives one source/target disposition and external-effect reconciliation.
Control scheduled occurrencesWhat changed after the baseline extraction?
A create/update/delete/event register with apply-once and dependency evidence.
Control the migration deltasHow do we decide the migration is acceptable?
Counts, balances, relationships, samples, and exceptions evaluated by domain.
Set domain acceptance gatesDid users receive the correct target access?
Positive and negative tests of capabilities, property scope, and removed access.
Verify effective permissionsWhy do historical reports differ?
Differences classified by scope, definition, timing, correction, presentation, or unresolved evidence.
Build a comparability bridgeCan the team still return to the source system?
A tested decision path with write ownership, delta capture, communications, and a point of no return.
Review the rollback boundaryGuides, references, and tools
Use the right format
Guides explain the workflow. References define the terms. Tools let you work through your own assumptions.
