Good point regarding the Moab license! I suppose I could get around any 
possible issue by running the new TORQUE pbs_server on the same storage 
node but listening on a different port.

Just before I saw your reply I raised the possibility of an in-place 
upgrade with my boss. Technically I can see how an in-place upgrade would 
be much simpler. Since this will be my first upgrade, I can't guarantee 
that I'll get everything done in X hours or even a single day, so I'd need 
to ask for more time. Our cluster is so new that not all users are in the 
habit of using Moab+TORQUE, so perhaps I might be able to convince 
everyone to do without Moab+TORQUE for a few days. I'd expect that future 
upgrades would go more quickly so I could just schedule a few hours on a 
single day for those.
