The new Design Studio for S32Platform 3.4 has some features I need and therefore migrating from S32DS for ARM 2.2 was the obvious choice.
What I did:
- Install DS 3.4
- Point to old Workspace, click on OK when asked to migrate.
- Open project, refresh, clean and BUILD

When checking the Project Properties this warning poppes up:
Orphaned configuration. No base extension cfg exists for com.freescale.s32ds.cross.gnu.arm.cortexm.exe.release.508611179

And when checking the Tool Chain Editor:
Orphaned toolchain com.freescale.s32ds.cross.gnu.arm.cortexm.toolChain.release.470831999 (Standard S32DS toolchain for ARM)

The register View is also empty:

Renaming the project yields:
Selection is empty or project(s) are out of workspace

The error log looks like this:

How do I fix this?
