Deployment Cutover Planning

Deployment cutover planning is the migration plan for replacing a marketing automation platform, CRM integration, or routing engine: sequencing data moves, dual-running old and new systems, defining freeze points, and reconciling contact state.

It is broader than blue-green deployment, which is only an environment-swap technique; cutover planning covers the whole switchover, including in-flight workflows.

A practical example

Example: migrating from an old MAP, you plan a two-week dual-run where new leads enter the new platform while existing nurtures finish on the old one, with a freeze on list edits during the final contact-state reconciliation.

What to evaluate before investing

  • Ask vendors what contact-state data they can export mid-nurture — enrollment, step position, wait timers — and in what format.
  • Ask whether the platform supports dual-running, for example by accepting leads while historical data is still loading.
  • Ask how the vendor recommends handling workflow state that cannot migrate, such as proprietary step logic.

Limitations and tradeoffs

Cutover plans protect revenue automations but cannot make incompatible state migratable; some in-flight workflows will need manual completion or restart, and the plan should budget for that work explicitly.
