seemless migration
Hi
Need to migrate a group of servers to a new T1 line as smoothly as possible.
These servers include all the usual. Dns, mail, http etc.
The reason is, Birch Telecom is getting out of the T1 bussiness and
dropping all the customers. The new provider will be at&t so this will
NOT happen again.
Birch will drop service on Jan 30. The new line will be installed on
Jan 18.
That doesn't leave much time to mess around.
Primary name server plan:
The plan is to duplicate the primary dns server. One week before the
switch, change the ip at the root. This will bring the primary down
ahead of time but give the world plenty of time to make the switch.
Meanwhile the 3 secondary's can handle things... As the original primary
continues to supply the secondaries..
Sites/Servers plan:
Set all ttl of all dns to 10 minutes 1 week ahead of time.
As soon as the new line is up and reliable, change both primary name
servers with a prebuilt bind setup. Ugghh Sounds like fun. :)
Then, Switch all servers to the new line and pray...
Any thoughts or suggestions or comments would be greatly appreciated.
