I have had to migrate my LR library from one user on my iMac to another user. I have noticed that I have 4 libraries (i.e. Lightroom 3 Library, Lightroom 3 Library 2, Lightroom 3 Library 3 etc) in my directory, and that they appear to be new versions when LR is upgraded. Am I safe to delete the older libraries when I have checked they are not being used?
Thanks!
