I've got a strange situation, I have a server that is connected to an old static IP on a totally different gateway, dns, subnet and a new static IP again with a new gateway dns subnet. I also have about 50 domains pointed to the old IP, I want to make this as seemless as possible so is there a way to activate both connections on one nic? Here is a little diagram of the network topology:

2 Internet Connections go into switch ==> One line comes off switch and into server(Everything is layer 2 only)

Yes, use vLans to connect both networks to the same NIC on the server.

Yes, this is called IP Aliasing.

If you want your system to be smart about routing (to avoid the problems with multiple default routes or asymmetrical routing), you can use policy-based routing.
