Move from MRP to ASCP

I know this question is about 10 years later than current topics, but my company is still using MRP even though they purchased ASCP.  MRP fits their needs for the most part, but they are starting to need more visibility into resource capacity.  Are there any good white papers on what is required to make the move from MRP to ASCP?  Or as an alternative, can they be run concurrently to ease the shock of making the jump?  EBS Version 12.0.6 (please don't laugh too hard)
