I have accidentally been switching between catalogues and have lost track of everything. I would like to have ONE catalogue combining two or three catalogues. Is there a way to start an entirely new Catalogue, combine the older catalogues into this new catalogue AND avoid having duplicates. The two or three catalogues have approximately 22000 photos each - both are named Lightroom 4, Cat 2-2-3 Lightroom Classic and Lightroom 4 Cat 2223 Lightroom Classic.
