The issue

Unlike component migration, instance migration involves upgrading only, i.e. CMDI 1.1 compatible instances will need to be upgradeable to 1.2 but there no valid use case is known for a conversion in the opposite direction. As is the case with upgrading components, this conversion should be mostly straightforward.

Special care has to be taken with CMDI 1.1 instances based on profiles that are in fact dumbed down versions of 1.2 profiles, see 1.2 -> 1.1 -> 1.2 roundtrip.
