moving DNS

[Tinus Nijmeijers <mlists@deephosting.com>]

just wanted to run this by some people more knowledgeable than myself.
please tell me if I'm wrong.

I need to move the data/sites/databases/mail from one hosting machine
(OLD) to another (NEW).

I can have OLD online for as long as needed.

OLD is also dns0.domain.net.

to move to NEW I was thinking this:

-move data from OLD to NEW.
-proxy all web-requests( rinetd), pop (rinetd), ftp (ftp-proxy) and smtp
(postfix transport) to OLD and forward to NEW
-at the registrar: change the IP of dns0.domain.net to the IP of NEW 
-change the zone files on OLD and NEW to reflect the move to the new IP
-wait a couple of days for everyone to catch up.
-take OLD down.

does this sound right to you?


thanks,

tinus.
