Re: [Quickfix-developers] FIX 4.1 to 4.2 and vice versa

Yeah, this is fine.  You might need to make a copy of the message first
if you are in C++ since it is passed to you as const.  If you are using
C#, a copy is already made for you under the covers so you are free to
modify it.  By the time a message you send makes it to the session, it
only sees it as a generic Message object anyway, so everything about the
message is determined by its contents, not the version or type of the
original object.

Similarly, when the exchange/broker sends a message back to the gateway, the gateway in turn forwards it to the appropriate client.

If the message contents wouldn't change other than the BeginString, is it as simple as changing the BeginString field in the message header, or will QF react badly to such a "rewiring"?
