Is it possible to use one catalog to access copies of the same image files, on another hard drive?
I have somehow lost the catalog to the images on my NAS (I'll call these Catalog A and Files A).
However I do have a complete matching copy of the image files and a catalog to these on a saved hard drive (Catalog B and Files B). The catalog is nearly 2GB
Can I use the catalog B to utilise the image files A on the NAS?
This would be a useful marriage if I can as it would avoid the hassle of emptying and reinstalling onto the NAS
I am transferring everything from an old PC to an new iMac
Thanks in anticipation

Yes, you can simply start using (a copy of) catalog B. The only thing you will have to do is 'relink' it to the images on the NAS. Right-click on the top folder in the folder panel and choose 'Update Folder Location'. In the dialog that comes up navigate to the same folder on the NAS and select it. You will have to do this for each top folder if you have more than one.

Let Lightroom make a catalog backup on quit. In the backup dialog, choose a destination for the backup that is not your internal drive.

To follow up on whatJohan has said, you should used TimeMachine to backup both the catalog backups and the master copies of the image files. Time Machine should be the system backup for all of your critical data files.
