I'm not sure which is faster/easier. Just joining one box at a time and then decommissioning or using replace_address.
this stuff is always something you do rarely and then more complex than it needs to be. This complicates long term migration too. Having to have gigabit is somewhat of a problem in that you might now actually have it where you're going. We're migrating from Washington, DC to Germany so we have to change TCP send/receive buffers to get decent bandwidth. But I think we can do this at 1Gb per so per box.
