Staged migration with a way back
Proposed interface concept Not released. A design for discussion, drawn in HTML and CSS; not a screenshot of working software.
During migration the same tool shows each wave’s progress per workload, throughput and source throttling, the delta-sync schedule, warnings with a concrete action next to each, verification checks, and the cutover plan — including the MX change and the rollback point. The figures shown are example data.

Shape this before it is built
This screen is a proposal. MSP design partners review concepts like this one against how they actually run customers, and say what is missing.
