[WIP] 658 659 move data

[bjrne]

Heavily WIP, profiles are almost gone (down to ~300 test failures now vs. 580 in the beginning 😁 ).
Help is appreciated! I left a lot of "TODO:" comments, just search for them and to what you can.
For the moment, I just commented all profile-related tests and stuff that ins't used at the moment but could possibly be reused later in this PR.
