Group Migration Plan
Step 1: Migrate
- Take a snap-shot of the entire development environment from the old SCM system and migrate this to ClearCase.
- While this is going on, development is continuing on the old SCM system.
Step 2: Update
- Once all the code has been migrated, then go back to the old SCM system and migrate just the changes since Step 1.
Step 3: Cut Over
- Lock down the old SCM system to prevent any more modifications
- Enable mirroring of updates from ClearCase to the old SCM system.
