Move the photos using your operating system and then reconnect in Lightroom via http://www.computer-darkroom.com/lr2_find_folder/find-folder.htm
Backups of your catalog must not be on the same hard disk as the working version of your catalog.
Thanks--the article is detailed and appears to completely answer my question. I am simply going to copy my photos over to the new NAS and reconnect them using LR.
I am curious about your backup comment--currently my catalog backups are on the same hard disk (iMac) as the working version of my catalog (as they always have been and never created a problem)
What will happen if I do not move my backups off my Mac first?
After I reconnect in Lightroom, can I then continue to keep catalog backups on the Mac as I did before?
The problem with having backups and working catalog on the same hard disk is that when this disk fails (and it will fail someday), now you have zero copies of your catalog. I'm guessing that you won't be happy about this. If the backups are on a different disk, and the original disk fails, not really a problem.
Moving the backups has no effect on Lightroom, but does provide greater security, as I explained above.
Thanks for the clarification. I actually perform scheduled backups of my backup to another drive, so I should be good
Thanks so much! This worked like a charm--I would advise it for anyone looking to move their photos. I understand that using Lightroom to move photos can have problems.
The only thing I would recommend is before moving your original files is to perform an LR Catalog backup so that absolutely everything is matched up and the Catalog refers perfectly to the photos.
I also backup my catalog backups automatically to a different drive.
