Combining repositories

Revisiting this topic from last September.

Throughout my project’s history, the dvc repository has been a few different places.
Let’s say I copy all the files in all the repos’ .../files/md5 into a single location (using rsync, cp, etc.).
Now when I check out an old git commit, the .dvc/config might point to remote = old-place. Can I then edit the .dvc/config and change it to point to the new repo location and be able to fetch/pull/push from/to that location?

Yep, that should work without a problem (assuming you were using the same major dvc version at both points in time).
