Read that "patching" configs is something which is done in order to export/import only parts of the configuration. Gave it a try: Exported the vanilla PA540 configuration and compared with the PA220 configuration. Removed the whole virtual router section. Added a logical router section I took from the PA540 configuration. Added "<advanced-routing>yes</advanced-routing> to the exported configuration.
Import works and gives no longer an error 🙂
Still I think the Virtual Router migration script which runs when you manuall activate "Advanced routing" in the settings, should be run when you import an old configuration into PAN OS 12.x.x
