Subject upgrades and old clients
Date Thu, 20 Nov 2008 09:11:03 GMT

As we prepare to do a upgrade on our cluster this weekend, I had to stop 
and think what a PITA it is to go around and upgrade all my clients at 
the same time, especially if we have to roll it back again.

So I was wondering how hard it would be to make the RPC mechanism that 
the clients communicate on able to talk >2< versions of the protocol. 
'N' and 'N-1' so that we could upgrade the cluster, and slowly upgrade 
the clients, possibly even on a secondary port.

or am I missing something in the manual that allows this to happen already?
