Map meaning as well as field names
A field called status may represent a different stage in the new system. Document the meaning, allowed values and required format of each field the workflow uses. Include defaults, blank values and custom fields. Use real-shaped test records without unnecessary personal information. A hypothetical customer marked inactive in one platform might remain visible but blocked from new work in another. Confirm the business consequence of the mapping instead of assuming that two similarly named fields behave the same.
Decide what history moves
Separate current records, unfinished tasks and historical evidence. Not every old record needs to trigger fresh automation in the destination. Define which records should migrate, which remain available for reference and which require special handling. Preserve the relationship between source and new identifiers where possible. Otherwise a later update may create a second record rather than modify the migrated one. Document how staff will locate older information after cutover. Avoid deleting the old source simply because the new platform displays the expected record count.
Set a precise cutover boundary
Choose when the old workflow stops accepting new work and when the new path starts. Account for queued events, delayed notifications and items already in progress. Decide who owns the transition and how to pause intake if reconciliation reveals a problem. Do not allow both paths to write the same business action unless their relationship is deliberately designed and tested. A time boundary alone may be insufficient when events arrive late; record the last processed identifiers or other reliable progress marker supported by the source.
Compare outputs before widening scope
Where practical, run a controlled comparison in which the new workflow prepares results without making live changes. Compare those results with the approved expected output. Include unusual but valid records, not just a clean sample. If a separate test environment is unavailable, agree a small, clearly identified pilot scope and recovery process. Check relationships as well as totals: the right number of tasks assigned to the wrong customers is not a successful migration. Keep discrepancies visible until each is explained or corrected.
Reconcile existence and content
Count expected records and verify a sample of their actual contents, including links to related records. For critical items, use complete checks appropriate to the risk. Two systems reporting zero differences can still both be missing the same source work, so compare against the original intake or another independent reference. Review failed and skipped items separately. Confirm that downstream notifications and staff views use the new records correctly. A connector returning success proves less than a staff member finding the correct item in the destination.
Keep rollback realistic
A rollback must account for records created since cutover, not just switch the connector back. Define how that new work will be preserved and reconciled. Retain the old configuration and necessary access for the agreed transition period, while avoiding uncontrolled simultaneous processing. Once the new path is accepted, update monitoring, support instructions and account ownership. Retire obsolete schedules deliberately and verify they have stopped. Migration is complete when the new path works, unfinished work is accounted for and the old path cannot unexpectedly resume.
