Transferring a production server from NYC2 to NYC3 with minimal downtime
I have a production server that I would like to transfer from NYC2 to NYC3. The problem is that we will be issued a new ip address once we switch. With the new IP address we would need to update our DNS records which of course would mean it would take some time for those changes propagate.
The best strategy I’ve come up with so far is boot up the new vps - and point the old vps to the new vps’s database while we wait for the DNS to switch over.
My question is: What strategies can I use to make this switch as smooth as possible with zero to minimal downtime (ie. less that 30 minutes downtime)?
