LR catalogue backup, storage and access
I am moving from LR 4 to Creative Cloud. Currently on my desktop Mac, the LR back up catalogue is named Lightroom 3 Catalog-2-2.lrcat. I didn't realize that my Lightroom folder has placeholders for other catalogues up to LR4 but I am not sure if anything is in them and concerned if I access them I wont be able to get back to my current catalogue. So i would like to know if anyone can suggest whether I should migrate my current catalogueLightroom 3 Catalog-2-2.lrcat to the folder named Lightroom 4 Catalog lrcat and if so how?
Once that is resolved, I will be adding a Creative Cloud license to my Laptop and also needing to copy all of the data from my desktop lightroom to an external drive and then accessing that data from my laptop. I would appreciate any suggestions as to how that is best accomplished. Thank you
