Mixing 2.2.12 and 2.3.x in murder environment

Thanks Patrick. The reason we want to speed up the upgrades is because of the 2.2.12 threading problems - high cpu, locked up mupdate. Ideally we would upgrade mupdate to 2.3.x and then upgrade the front ends and back ends a little later. Do you think 2.3 mupdate would work well with 2.2.12 backends?

What mupdate problems are you seeing with 2.3?

Only reason we went with 2.2.12 for frontends is that when we first 
installed 2.3 it was in the summer and 2.3 didn't work as a frontend. That 
has been fixed now. Only reason we haven't changed the frontends to 2.3 is 
that we're busy with other stuff at the moment.

There are some problems with the murder master in 2.3. We use it anyways 
since it fixes some threading problems that would occur in 2.2.12

For example, 2.2.12 back ends, 2.3.3 mupdate server (it is 2.2.12 now) and 2.2.12 front ends. Or, if anyone did the upgrades from 2.2.x to 2.3.x in another way, would you mind sharing your thoughts.
