How to go about changing Kerberos domain ?

[Laura Smith]

Let's say I've got two KDC's:
- foo.example.com (master)
- foo1.example.com (replica)

They operate the example.com kerberos domain.

There is a possibility I will need to change the host DNS so they will be known in the future as:

- foo.example.org
- foo1.example.org

How would I go about this ? My DNS entries under the present example.com look as follows:

_kerberos TXT "EXAMPLE.COM"
kerberos CNAME kbr
kerberos-1 CNAME kbr2
_kerberos-master._udp SRV 0 0 88 kbr
_kerberos-adm._tcp SRV 0 0 88 kbr
_kpasswd._udp SRV 0 0 88 kbr
_kerberos._udp SRV 0 0 88 kbr2
_kerberos._tcp SRV 0 0 88 kbr
_kerberos._tcp SRV 0 0 88 kbr2
kbr A ;REMOVED
kbr AAAA ;REMOVED
kbr2 A ;REMOVED
kbr2 AAAA ;REMOVED
