Existing Plans and Templates
Users will have the ability to decide whether or not to apply a cost model to a plan.
For example, users can choose to leave a plan (or template) created in cost model 5.3 in its current state. Should the user later choose to update an assumption or a default value in that plan, the plan values will recalculate using the logic from the 5.3 cost model.
Conversely, the user can choose to update a plan (or template) created in cost model 5.3 to cost model 5.4. In this case, the user's overwritten values will be preserved but all default values, logic, and tasks will be based on cost model 5.4. The plan labor and cost values will change to reflect the new model.
Cost models prior to version 5.3 have not been preserved; therefore, plans (or templates) locked to earlier versions (5.2 and less) when upgraded, will be upgraded to 5.3 at minimum, with the capability to upgrade to 5.4 on demand.
