Hi! I've (finally) found how to do the standalone upgrade (with no thanks to Adobe, who seem determined to force everyone down the CC path!)
Butnow I appear to have both 5.7 and 6 installed on my PC, and I note that LR6 appears to have made a fresh copy of my most recent catalogue.
My question is - can I now safely uninstall my copy of LR 5.7? Or does it share something which might cause LR6 to stop working?
LR6 needed to make a copy and upgrade the catalog to work with it. The catalog is not backwards compatible.
One you are sure that the conversion went perfect, you can uninstall LR5 and backup(remove) the old LR5 catalog.
Very many thanks indeed, F. McLion!
I'll be doing that today!
