Hello,
I am guessing that you are using CodeWarrior Classic, because you have not mentioned this information in your post.
I think that the easiest way will be the following (this steps also match for renaming a project without point 4):
1- Create new PE Project with MCU that you use
2 - Using “Import…” menu command import all PE settings from origin project (import menu command is available in pop-up menu of "Project Panel" window by clicking into white space)
3 - Copy Events.c, Events.h, and main module from origin project into new one (eventually also user modules)
4 - Set PE components according to another PCB
best regards
