Changing a source location

I recently moved a significant (700+ GB) source FROM my hard drive TO a dedicated external SSD. It is an exact copy of the file structure, i.e., a deep rsync copy. I don't want to unnecessarily have Peakto re-analyze everything it has done (faces, aesthetics, etc.) when I re-map it to the new SSD.

What is the best, most efficient manner for accomplishing this change? Thanks in advance!
