Pick a strategy honestly
Rehost, replatform, refactor - each has different cost, risk, and upside. Don't conflate them.
Parallel running is the friend
Running old and new in parallel turns a high-stakes cutover into a low-stakes observation period.
Rollback is mandatory
If you can't roll back, you haven't planned.
Key takeaways
- Match strategy to risk tolerance
- Parallel running de-risks cutovers
- Rollback plans are non-negotiable
