I find a trick to update code on an AX system with multiple AOS(s) without restarting the AOS services.
Let say you have 2 AOSs for users to access. If you do the code in AOS1. You will need to run AX on the AOS2 and compile the code you just changed in the AOS1. That way both AOSs will be updated transparently to users.
Of course in some cases, users will just have to restart their session to get the new update.
