I don’t know what your 7TB is, but I know what my TBs of data are and my approach in this situation was to just nuke anything that was available from its original source, backup the few things that were orphaned to an external drive and pull everything down again onto the new array.

Interested in the community’s view to this too. This is what I’ve been using and it’s been flawless.
