Our production UM implementation consist of a quorum of three (3) UM realms version 9.10. What is the recommendation for applying SAG fixes without taking a scheduled production outage? For example, I can take one UM realm offline and apply SAG fixes to it and then bring that patched UM realm back online and allow it to rejoin the quorum.
However, I am concern that the quorum will then include one patched UM realms and two unpatched UMs. Is it a problem that the three UMs realms will be at different patched levels for a short period of time during my patching rotation?
