What Is a Phased CMS Migration?
IntermediateQuick Answer
TL;DR
A phased CMS migration moves content and functionality to a new CMS incrementally rather than all at once. Instead of a single "big bang" cutover, you migrate one section, content type, or market at a time — running old and new systems in parallel throughout the transition. This limits the blast radius of any issues, lets teams learn and adjust between phases, and keeps the business running without extended downtime.
Key Takeaways
- Migrate content in logical phases: by section, content type, or market/locale
- Run old and new CMS in parallel during the transition period
- Phased migrations reduce risk compared to big bang cutovers
- Each phase is an opportunity to learn and improve the process before the next one
