slexpress:Does backing up the library in the old version and restoring it in the new version work? It should. Never dawned on me to do that. I have copied the NGDatabase folder from the old version to the new version in the past but did not do that this time.
I use Control Panel/Reset and Backup/Backup Library. No need to copy folders. I find this feature very useful, for instance for backing up different (sets of) Project Bins, so that when I revisit a project, I only have to restore that Library file. Avoids clutter. Of course, after a while, some assets have gone missing as I tend to move files and folders around. So I'm trying to find ways to quickly locate and relink them again (that's why I started this thread).
