32 to 64 bit -- murder and replication

Hi all,

To throw another 32/64 question on the fire here, I'm hoping to upgrade the 
ancient 1.6 (yes, I know!) install here to 2.3, and then we're going to use 
the murder to help us break out of the single giant 6800 we have and move 
to the distributed model.  However, for a time, the 32 bit code on the old 
server is going to need to play nicely with the 64 bit code on the other 
servers, both front-end and back-end.  We'd also like to get replication 
into the mix here at some point, and may have the same split.

Everything will be running the same code, but it will be a different build, 
naturally (the old housed on Solaris 9, the new on Solaris 10).  Can anyone 
think of any nastiness we might run into along the way?  Ram's warning 
about the seen flags means I'll probably dump the seen databases before 
migration just to be safe, but I think we can handle migration issues. 
It's the ongoing interop issues I'm worried about.
