Our company is trying to move all our servers to a new collocation, the problem that I have run into is that I would really like to have 2 environments running at the same time so that we don't have to shut down all servers move them to Dallas, TX from Northern California and then hope everything goes well when we start things up there. We have a dedicated 10Mbps line between our office and the Collocation(Dallas, TX). We are going to have 1 web server, 3 Application Servers and 1 Database server. All the application servers are tied to eachother and the web server like a spider web unfortunately. We have all redundant servers that are available to us. Should I setup clustering and then run them simultaneously? I need some guidance if anyone has done this before. Thanks a million and I will reward the answer as many points as I can.
