[Freeipa-users] Migration from FreeIPA 3.0 to 4.x

[Christophe TREFOIS]

I’m not expert but I think ipa-replica-prepare is depcrecated in 4.4 as the procedure become more simple.

I think setting up a new cluster of CentOS 7.3 machines and setting up replicas against the old cluster is sufficient.

What do the experts say?
