     I think I'm on the home stretch :). However I am running into a 
issue after switching the backend. The switch command completes 
successfully. Bind starts but I get errors when attempting to run this 
command after reboot.

samba_dnsupdate --verbose --all-names

I get this error for all updates.

TSIG error with server: tsig indicates error
update failed: NOTAUTH(BADSIG)
Failed nsupdate: 2
update(nsupdate): A gc._msdcs.domain.local
Calling nsupdate for A gc._msdcs.domain.local (add)
Successfully obtained Kerberos ticket to DNS/DDC1.domain.local as DDC2$
Outgoing update query:
;; ->>HEADER<<- opcode: UPDATE, status: NOERROR, id:      0
;; flags:; ZONE: 0, PREREQ: 0, UPDATE: 0, ADDITIONAL: 0
gc._msdcs.domain.local.   900     IN      A

I can connect to the server via. Windows DNS Manager and browse.
