Re: [cobalt-users] PLEASE advise: Need a clean transfer from RaQ to RaQ

[DSL West Ops <lists@xxxxxxxxx>]

We're doing kind of a similar move.  Our plan was to transition the 
DNS and the mail/web services separately.  The DNS transition takes 
an undefined amount of time due to propagation delay.

Here's what we're doing:

1) Set up the new services on the new Raq3i servers.
2) Build new a & mx records in the new Raq3i servers pointing to the 
new locations.
3) Leave the Internic records intact, pointing to the original DSN servers.
4) Change the mx records on the original DNS servers to point to the 
new mail servers on the new Raq3i servers.  This is the only dicey 
part, since hosts that got a DNS lookup within the TTL time of the 
DNS records will point to the old mail servers.  We may have to set 
up a forward from the old servers to the new.
5) Change the Internic domain records to point to the new DNS servers.

I believe this method is what you're proposing as well.

Like you're we're open to suggestions.  Particularly about point 4.

Bill @ DSL West
