So it turns out that it wasn't the cluster compatibility that I missed, but
that the data center compatibility level needed to be updated to 3.6 as
well. I just didn't read the error message closely enough.

For the record, I ended up using 'yum history' to roll back the updated
packages, and was then able to start the engine, change the datacenter to
3.6, and re-run setup successfully.

engine-setup should be completely transactional and it should rollback by itself on failures; could you please share engine-setup logs from your failed attempt?
