Prettyphoto with migration to new computer

I’ve been going through all the posts on transferring RW to my new computer for a fresh start (eliminating 8 years of RW upgrades and three versions of Office, etc.). I’ve fixed a lot of the issue by bringing over the RW files I could find in the Library.
But Prettyfoto3 does not work. and I have several hundred pages of prettyphoto pages with thumbnails and links.
Searching with pretty or anything like that does not show anything.

What files are hiding? and where?

Mine is here:

/Users/yourname/Library/Containers/com.realmacsoftware.rapidweaver/Data/Library/Application Support/RapidWeaver/Stacks

The stacks name is MS_prettyPhoto3.stack
