copy of raw pictures from one HD to another new hd. what to do with the catalogus?

Dear reader of this discussion.

I have a new hard disk. And I copied all my original raw pictures from my old hard disk to the new one.

The catologus contains all the work, processing , ameliorations of the original pictures on the old place , hard disk.

How can I arrange that the good processing of this pictures (the catalogus) is going to / are joined with the (same) pictures on the new hard disk?

Greetings, Eddy
