I have a corporate server at www.mycorp.com
) IP Address: xxx.xxx.xxx.xxx
Switching over to www.mycorp.com
) IP Address: yyy.yyy.yyy.yyy
Before I change the nameservers for www.mycorp.com
to point to the new IP address, I want to set it up so that there is no interruption to the live site and no email is lost or interrupted.
As far as the live site, can I set up the mycorp.com homepage at the old server to redirect to www.newserver/~mycorp
, then change the nameservers to point to the new IP address? Does that avoid the propagation time lag?
As for emails, how do I set up un-interrupted service. Both the old and new accounts will have the same domain name. Isn't there a way to use the IP address when setting up an account in Outlook Express, so I could have each user checking email at both accounts until the propagation time has run out?
Any help appreciated because I have to get this done in the next 24 hours and there are 11 cranky salespeople addicted to email that cannot survive any interruption.
