Server Migration to another ip address
 

Hi,

I have one server installed with plesk hosted on this ip eg 203.117.83.23. I will need to migrate this server to another ip at 203.118.25.87.

The A/MX/DNS records will need around 24hours to propagate. During the propagation period, i will need to direct all http/mail request from the old ip to the new ip.

I thinking of setting up a new server using this 203.117.83.23 ip address and direct all the mail/http traffic to the current server hosted at the new ip, 203.118.25.87. But how can this been done?

May i know has what will be the best way to move the server to this new ip address with little downtime in http and mails?

Thanks

anyone ???

I believe it's possible to set up a server to have more than one ip address. In your case, you could set up the same server to map to both the old and new ip addresses. Then, when all the records propagate, you can remove the old ip. I don't know if you would have to forward any mail if it was set up this way.

Hope this helps and good luck!

An alias will work, as will a port forward on your firewall (you do have one, right?). Until your PTR <-> A records match, send outbound mail on your old IP, or remote MTAs may reject your mail.
