Find a workable seam
Choose a workflow with a clear interface, understood dependencies and measurable acceptance criteria. It gives a migration team a bounded place to learn.
Keep reconciliation visible
During a transition, old and new systems may coexist. Define record ownership and comparison checks so that differences are found before they become operational confusion.
Make rollback credible
A rollback plan must include data and integration behavior, not just an older application build. Agree the conditions for pausing or reversing a release.
