Issue

How to change hostname or IP of an IPA server.

Resolution

The official supported way how to rename the IPA server is the following:

  1. Create another replica of an IPA server with desired hostname/IP.
  2. Verify that the replicated server is working properly.
  3. Disconnect the "old" IPA server.
  4. Test all functions against new IPA server with the new hostname.
  5. Decommission the old IPA server.

Root Cause

There is no official way how to achieve this task without replication. It is too complex and dangerous to do it on a single machine.
