Five observable signals from 500+ migrations that your team is ready, plus a readiness scorecard. If 3 match, you should be scoping this quarter.

After 500+ migrations, the patterns are predictable — and they're not what most teams expect. Five failure modes, five success predictors, and where the time actually goes.

So we built our own — with AI-powered PL/SQL conversion, zero-downtime CDC cutover, and row-hash validation.
