I have had Lightroom since the third edition, and since then I saved every import under it's own catalog (due to my lack of reading and wanting to jump right to the editing). Now after reading and watching tutorials, I know that it's 1 catalog (or a few more), that contain different collections. So now I am going to take on the daunting task of going through all the catalogs and making them collections. From there I would like to import them into catalogs classified by the category. My question is, can I import collections from different catalogs without having to open each catalog, or do I have to open each catalog and export each collection? Thanks for your time.
Don't worry about collections. Just export each separate catalog. Then import them into a master catalog.
