Transfer all my customization from CP8 to CP8.5

I’ve upgraded from 8.0.35 to 8.5.10
From what I gather, it treats the upgrade as a fresh install, in its own folder and everything… ok…

But now, all my customization is missing:

Plugin Collections
Workspace Templates

All the things I did in ver8 to set it up the way I like it…

How do I get it all into 8.5?
