Maybe I had it backwards then, I remember looking at upgrading and because
I have BDC's at remote locations there was a problem I could not resolve.
This was during the 2000 beta though so it's also possible it changed or
I'm just remembering wrong but my conclusion was I would have to take the
BDC's down, upgrade the PDC's, then upgrade each BDC before bringing them
back online.

What about replication from a BDC back to the PDC if someone at a remote
location where there is only a BDC decides to change something?
