Recovering Images from a new location?

Would appreciate some advice for the following:

Last week I had a problem with my Lacie RAID enclosure, which has resulted in me buying a new drive for expediencies sake (at some point I'll find a suitable enclosure and try the drives). All of the content was protected using Backblaze, which I'm currently part way through recovering. For whatever reason, I'm unable to rename the new drive to same name as the old on (Thunderbolt HD does not seem to be valid, so it's called Thunderbolt).

I now have enough recovered to be able to see my LRC catalogs and some of the photograph directories and I've come up on the issue of the catalog not recognising the images because they're not in the 'location' it was expecting i.e. although the directories are correct, the HD name is not.

Can I repoint the catalog and retain all of the edit detail I have and, if so, how do I do it?

Thanks for reading, David...
