I recently upgraded from Lightroom 5 to Lightroom 6. When opening my previous catalogs, it would ask to upgrade the catalog. I said yes, and then it renames them to same file name with a "-2". After doing that, do I need to keep the previous files made in Lightroom 5? Get I delete them? Seem to be doubling the files and taking up space on the hard drive.
It's up to you. I'd generally advise keeping LR5 and the last LR5 catalog on the system for a few weeks, or at least until I was certain that I'd never be going back to LR5. Once you reach that point, and you have several new backups of the LR6 catalog, then it should be OK to uninstall LR5 and delete the LR5 catalog.
Ok, thanks Jim. I think I will move the LR5 files to an external hard drive before deleting.
