After disk failure how do I reconnect my images to the backup?

[abridge444]

I've had a complete failure of my RAID with 10s of thousands of images.

BUT...I have a complete, up to date, backup. Yea team!

Is there a simple way to have Lightroom Classic reconnect to the new drive without doing it folder by folder?

Run on a 2019 Mac Pro with oodles (highly technical term) of memory etc.

If the Lightroom Folder panel is not showing the folder hierarchy like your computer's file browser does, right-click on a folder and select "show parent". Repeat as needed.

Then select a top-most missing folder, right-click, "find missing" or "relocate", navigate to the new drive. Repeat as needed. Lightroom is auto-correct all the subfolders and files under the corrected top-most folder.
