I first tried setting the policy, but got "Error while executing action:
The set cluster compatibility version does not allow mixed major host OS
versions. Can not start the cluster upgrade."; I guess this is because
my hosts are CentOS 7 and the engine is CentOS 6?

I tried changing the engine config to skip that check from comment 10
step 3, but got:
- Can not start cluster upgrade mode, see below for details:
- VM HostedEngine with id 4a035efd-a041-4e46-84db-01cf79400913 is
  configured to be not migratable.

I did the SQL update from comment 1, and then I could set the policy.

However, I still can't change the cluster compatibility version.
