[Freeipa-users] Upgrading from 3.0.0 CentOS6 to 4.2.3 CentOS7

[Ash Alam]

Most of the clients in my env are centos 6.6 with ipa 3.0.0 client
installed. I if bring up a replica on centos 7.2 with ipa 4.2.3 server and
then start phasing out the older 3.0.0 servers. Will the client that are
still running the older client software still work?
