Re: I have mistakenly created two separate catalogs, one in 5.6 and one in Lightroom 5 original. The latter is on my external drive, the former is on my hard drive. How do I merge them and upgrade the 5.0 main catalog?

OK Jim Hess, that step is done.  So on the hard drive, can I now delete:

1. the "extra" LR catalog?

2. the Elements 10 Catalog (which I had previously imported into one of the LR catalogs?

That leaves me with a single catalog on an external drive.  The only question is: what about backup catalogs? how do I determine where my "new consolidated" catalog is backing up to?

thanks in advance.
