Subject Re: Maximum node decommission // bootstrap at once.

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

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.
