I need input from my BPN friends.

I have one LR catalog, but the images are on two separate external HDs. I'd like to combine all the photos onto one larger drive, but I of course have the need to maintain the folder structure and applied LR adjustments to the images. From what I can tell there are a couple different ways to do this, but I wanted to get your advice. LR can be a bit confusing when it comes to cataloging etc....at least to me. 😊

Cheers!

PS I'm on a MAC if that matters.
