- Changing the IP address is a minor problem. Depending on your
setup users may need to get new tgt's after the swap.

- Changing the hostname is a slightly bigger one. Depending on
your foresight in making CNAME records of the names in krb5.conf you
might have a minor or a big problem. If I were you I'd really
try and set things up so you don't have to change the DNS
name from what's in the krb5.conf files you've distributed.

- You need to create a new host/new.dns.name keytab for
the KDC and you'll need to change acl's on slave kdc's.

- It wouldn't be a bad idea to do this anyway, in case
something goes wrong. But if you don't change the software
you shouldn't need to reload the database.
