[389-users] Re: Advice to bring new servers into production

[Leo Pleiman]

My experience has been that the replicas and consumers have a unique id,
more than just an IP address which creates the trust relationship with the
master. If your goal is to simply maintain an IP so your clients don't have
to be repointed, I would build each new LDAP host and replication
agreement, and then as you decommission the old hosts use their IP address
as a virtual IP address on the replacement host. It would take a quick
restart od the LDAP service to start a listener on the virtual Ip address.
