How to setup a new master catalog

You don't say where you want the new catalog, or even why you want the new catalog. I point out that catalogs cannot be stored on NAS drives (only photos can be stored on NAS drives).

Depending on exactly what you did, you may not need a new catalog. If you just moved the photos to the NAS and left the folder structure/hierarchy unchanged, you don't need a new catalog, you can use the old catalog (from before the move) and just point LrC to the new location of the photos (instructions).

Otherwise, we need to know exactly step-by-step how you did this move.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.
