I have an existing project schedule with 4 Phases. Phases 1-3 are complete and Phase 4 just started. I have built a new separate schedule for Phase 4 due to changes, but was not sure of the best way to "Update or Implement" this into the existing 4 Phase Project Schedule schedule. So:
Should I Update Phase 4 by:
- Pasting new into existing (leaving current Phase 4 in place, making old inactive, for easy reference)?
- Pasting new Phase 4 into existing - over Phase 4 current items?
- Or update the dates and make changes to tasks that changed?
I would like to know the best scenario for maintaining the full scope of Existing Project with the new implemented Phase 4.
