Migration readiness is a decision system.
The strongest migration plans do more than list activities. They define what evidence will make the next decision safe.
Enterprise migrations often become difficult when teams treat readiness as a single percentage. A status color can hide very different realities: one interface may be tested, another may be understood only in theory, and a critical business process may still lack an owner. A useful readiness model keeps those differences visible.
Start with decision points
Write down the decisions that must be made before cutover: whether scope is stable, whether dependencies are understood, whether the rehearsal is representative, and whether the business can operate after the switch. For each decision, identify an accountable owner and the evidence they need.
Make dependencies explicit
Map interfaces, data flows, operational jobs, integrations, and the people who rely on them. A dependency is not ready because it appears on a diagram. It is ready when its behavior has been tested in the conditions that matter.
Separate confidence from optimism
Capture unresolved issues with their likely impact and a clear response. Some can be accepted; others require a mitigation or a changed cutover plan. The point is to decide deliberately, before time pressure makes the decision for you.
Prove the first day
A rehearsal should answer operational questions: Can users complete their essential tasks? Can teams detect and triage failures? Is rollback feasible within the available window? These questions turn cutover into a controlled business decision rather than a technical milestone.
The result is a readiness record that anyone can inspect: decisions, evidence, open risks, owners, and next actions. Its value is clarity when clarity matters most.
