Am I safe to delete old Lr catalogues?

[Adam81224]

I'd like to save space on my laptop.  I've got Lightroom lrcat, Lrcat v10, lrcat v11 and lrcat v12.  Am I save to delete all but those pertaining to lrcat v12?

Yes, but move them first to another folder, then open your most recent catalog and make sure it works to be certain that you didn't accidentally delete a needed file. Then you can delete the older catalog files.

Thanks Jill, confirming you'd put the catalogue on the bottom of the list Lighroom Catalogue.lrcat (the oldest one) into the file with the Lightroom v10 and v10-v11 once I've confirmed v12 is intact?

Yes, that's what I'd do. I think you can safely consider it obsolete because of the date it was last used.

The short answer is yes (you can in terms of the V10/11 labeled data files) but as mentioned, ensure all is well in the current version of LR with the V12 catalog first.
