Merging DNS servers

[Leroy Tennison]

I am working on shutting down a site which has an isc-bind server that is master for a domain and subnet which will exist elsewhere once the site is closed.  The few remaining systems don't warrant such a server.  My goal is to merge what remains of the domain/subnet into an existing server which is master for other domains/subnets.  My current thinking is to:
freeze changes on the server being retired (fortunately DHCP's DDNS won't be an issue by that point)shut down that servertake the data files (forward and reverse zone with associated journal files) and place them on the remaining servermake sure the data file types are consistentchange the the remaining server's type from slave to master for the zones in questionrestart the remaining server
Is this a good plan?  If not, how should I proceed?Anything I'm missing?
Thanks in advance for your input.
