Reconnecting missing files located on new external hard drive

Hello. Recently one of my external backup drives failed and it was the one which Lightroom 'knew' held my files for the the early 2000's. I have a new exteral backup drive that now has these files on it. Is there a way to direct Lightroom Classic to go there for all the files it cannot find? I am presently reconnecting the files one day at a time and that has gotten a little old and I figured Adobe probably has a way that I can tell LR that my files from 2015 say are now located on this new drive.

Any help with this would be greatly appreciated.

Thank you.
