Inventory the current system
Start by documenting the applications, databases, files, user roles, reports, integrations, automations, scheduled jobs, exports, and manual workarounds that keep the current process alive. Hidden dependencies are the reason migrations get messy.
Map data before moving it
Data migration requires more than copying fields. Teams need source-to-target mapping, cleanup rules, duplicate handling, validation reports, retention decisions, and ownership for ambiguous records.
- Data sources and record owners
- Required fields and optional fields
- Transformations and cleanup rules
- Validation samples and reconciliation reports
- Backup, export, and rollback paths
Plan the cutover like a launch
A cutover plan should define who freezes the old system, who runs migration scripts, who validates the new system, who communicates with users, and what triggers rollback. The plan should include timing, escalation paths, and post-launch support.
The migration is not done when the data moves. It is done when the business can operate with confidence.
Stabilize after launch
Post-launch support should be part of the engagement. Users will find edge cases, reports may need adjustment, and integrations may need tuning. Planned stabilization prevents a successful migration from turning into unmanaged cleanup.
Common Questions
What should be included in a migration assessment?
A migration assessment should include system inventory, data sources, users, integrations, reporting needs, security requirements, risks, timeline, and validation approach.
Should the old system be shut off immediately after migration?
Usually no. Most migrations need a controlled transition period, backup access, validation, and a rollback or recovery plan.
