I've been trying LR4 beta on a number of pictures that are in my LR3 catalog as well as new pictures that I only imported into LR4 beta.
When I get the release version of LR4, what should I do so that I have one LR4 catalog that includes everything from the LR3 catalog, except those also processed in LR4 beta, and everything I've processed with LR4 beta, in both cases including all appropriate adjustments and keywords? In other words, I'd combine the LR3 and LR4 beta catalogs, but LR4 beta would supersede in the case of overlap.
