Trying to sort out a historic mess from multiple users on my machine. I have 2 versions of Lightroom on my Desktop.....5 and CC. There are multiple catalogues and there are thousands of 'Missing files' as i suspect files have been moved from the hard disk to external drives....is there a way to sort this out without spending months doing it......start again and import all images from the multiple disks? ...I assume by doing this I'd lose all the LR editing! HELP!
Lightroom 5 and Lightroom CC catalogs are not compatible with each other. Lightroom 5 catalogs can be upgraded to Lightroom CC, but not the other way around. You say that you "suspect" that files have been moved to external drives. You don't know, is that correct? Multiple users. How many. Thousands of images. How many thousands of images? What operating system are we talking about? How many external hard drives are we talking about?
