Oh, you really need to destroy and recreate the replicas here.

Correct. The searchbase doesn't change. Did you change the DNS name as well?

Take a look at the 10.2 version of changeip, it's a shel script that might give some clues.

I would:
1. Destroy replicas.
2. Change IP on the master.
3. Rebuild replicas.
If the hostname changes, then there might be larger issues. You can always dump the user data out, demote to standalone, massage the data, and then re-import it if you run into problems. Check our article on LDAP migrations for a how-to on this.
