Migration Sprints
Baseline Sprint Dates
MHHS Migration starts in October 2025 and runs until May 2027. To keep things structured, Migration will be delivered in nine sprints, each with a Planning, Execution and Retrospective Phase.
At a high-level, the phases cover the following activities:
- Planning Phase is when Suppliers will submit their migration plans (either a forecast or daily committed) via Kestrel. This is consolidated into a Baseline Schedule. Please note that all Suppliers need to submit a migration plan as part of each sprint planning cycle.
- Execution Phase is when Suppliers will execute migrations.
- Retrospective Phase is the period post-Execution to capture lessons learned from the sprint.
The table below provides the dates for each of those phases, for each Migration sprint.
For more information on the Current Migration Sprint please view the Current Migration Sprint page of this website.
For more information on how sprint cycles work please see the Migration Framework and the Migration Sprint Cycle Dates document on the Migration Baselined Documents Repository page of this website.
