It sounds to me like you want SEP to demigrate the files and restore them to their roginal locations, is that correct?
If so, then the "Scan all files, forcing demigration (fills drive)" sounds like your ticket. Just make sure you do proper planning and ensure that (a) this is definitely what you want to do, and (b) you have enough free disk space available.
