Client/Server version (in)compatibility
Hello,
I'm currently running a 4.0.1 server with 4.0.1 clients. I'd like to
upgrade everything to 5.1.0, but not at the same time. Ideally, I'd do a 2
stage upgrade where I first bump the server to 5.1.0 and then the clients.
Are there any known compatibility issue between a 4.0.1 client and a 5.1.0
server? I ask because in my testing there appears to be some problems. I'm
running 4.0.1 clients against a 5.1.0 server and see errors similar to the
following in the servers log over and over and eventually run out of heap.

Does anyone have any input on this? Is there a recommended upgrade path or
a client/server compatibility matrix floating around?
Thanks,

I believe I was told there was some kind of multi-step upgrade path
from old 4.x releases to new 4.x releases (if you want to upgrade the
server and multiple clients with minimal down time), but as far as I
know the folks who worked that process out haven't gone to 5.x. I can
try to get more details if the upgrades within the 4.x series are
still of interest.
Thanks,
Aaron

Chances are there are some sizable incompatibilities between ActiveMQ
4.0.1 and 5.1 simply because the time between those releases is about
18 months. If you're going to upgrade the broker to 5.1 then I'd
recommend upgrading the clients at the same time.
