As the dust settles in the aftermath of a successful physical data center move, I'm nursing my bruised and cut hands, kicking back with a Scotch, and reflecting on what went right. I said "successful," but actually there's no such thing as a failed data center move: If something's going wrong, there's nothing you can do except keep working until everything's up and running.
But a successful data center move is no accident. Whether it's a data center relocation or new data center build-outs, detailed plans must be made months or even years in advance.

There are a number of ways to move a data center. If budgets and skill sets allow, the easiest method is to build a brand-new data center in the new location, drop high-bandwidth links between the two, and use virtualization tools to migrate all the virtual machines from one site to the other -- live.
