Is there a guide for migrating an existing S32DS-PA project to a new (but similar) processor? e.g. from MPC5748G to MPC5748C.
from my point of view such a document does not exist. But if you want to migrate from MPC5748G to MPC5746C, main differences are number of cores, amount of memory and clock settings. So if you focus into these areas, it should not be difficult to migrate your project.
If you have any specific question about project migrating, please feel free to ask.
