Joe, I chose your #2 method of moving my DB servers (4), over the course of a few weeks during the summer of 04. I believe both methods has merits and I'll wager you won't have trouble in any case. The only caveat with method #1 is if you've made some mistake in the configuration of one DB serve

First of all, thanks to all who've responded, especially John Harris, Brian Sebby and Jeffrey Hutzelman. It looks like mixing the TransArc & OpenAFS fileservers isn't going to be an issue - good, as less trouble is always nice. I'll just bring the new systems into the mix and vos move stuff over
