p.1 #6 · Re: FIXED - LR4 Did Not import my LR3 collections
I went back and manually opened my main LR3 catalog in LR4 to trigger the conversion again and re-saved it. In the original conversion it auto selected the catalog and the image count is slightly different (~32500 vs 32300). Apparently it was not the correct one before. However it still should have had plenty of collections.
