Provide a tool to migrate from IPA to IPA.
Currently IPA can migrate users and groups from a generic LDAP server, but if you already have an IPA deployment there is currently no mechanism to migrate IPA-specific data such as SUDO rules, HBAC, automount, hosts, services, etc (these last two may not be possible as re-enrollment of the client is required).
Unless we can preserve the kerberos keys and certs and migrate them to the new system. Thsi would generally mean that we carry over all the master keys and certs too.
Simo had worked out a way to preserve the Kerberos master key long ago. I'm not sure if it is still applicable today.
My thought was that you end up with a new Kerberos master key and a new CA, which means that all migrated principals need new keytabs, and certificates are excluded from the migration.

From Pter Spacek:
May be that we could provide a tool for FreeIPA domain rename, so you can create replica, disconnect the replica and then rename the FreeIPA domain to something else (renaming would include master-key regeneration etc.).
This solves two problems at once:
