Changing IP Address/DNS
I'm looking for some guidance on setting up ISPConfig 3 on a server which uses a specific IP address and domain name, which will later be changed to a new IP address and domain name. One of our servers is being replaced, and we want to setup the software on the new server and move the sites to it, then once it's up and running, just switch the server IP addresses and domain names so all requests go to the new server instead.
If following the Ubuntu 10.04/ISPConfig 3 Perfect Server guide, which files will need to be edited after installation to complete the transfer? It's important that this goes smoothly since a few busy live sites will be getting moved.
I can't just fake the correct IP address on the new system since it's an EC2 instance that gets its static ip address from a DHCP server. The only way to make the switchover is to disassociate the elastic IP address from the old instance and associate it with the new instance, at which point all the DNS information that ISPConfig3 (and all the other applications) was installed with will no longer be valid.
