I would rather move the folders to where my New LR4 catalogue resides--this will make things less confusing--any tips for that??
Not really. The catalog can be on drive A, the images on drive B. The key is LR needs to know where the folders reside. IF you move them outside of LR, then it has no idea what you did. You then have to relink them. You do this within LR. Once done, you can move the folders or files anywhere you wish. But do it
within LR! It can move, copy, delete documents. If you do this within LR, it ‘knows’ where the files should be.
