Changing DNS forwarder server

I'm making a big change in our network.
For outbound Internet Host to IP resolution, our domain controllers go
to a
central forwarder server which has DNS installed on it with root hints
of
well known top level DNS servers on the Internet. So this server is
doing all the resolving of Internet host names for clients within our
network.
The plan is to change that server to point to a different server.
My plan for doing it is to basically stop the DNS services running on
the
current one and point the domain controllers to the other one (via the
forwarders tab in the DNS properties).
When I go into the current one and look a the Cached Lookups, there is
a massive amount of DNS entries from all over the Internet. Also, the
SOA record in the Cached Lookups is under .(root) > net. Is it normal
for that to be there? I'm thinking that SOA record was probably
manually put in there (but not sure). Should I put those same SOA
records into the other server before I cut over, or should I let it
start populating on it's own?
I'm also thinking that speed to the Internet will seem slow at first
but will speed up as the cache is filled from user queries to different
websites on the Internet. Does that seem like a plausable theory?
Help will be much appreciated.
