I am upgrading from 9.1(1a) to 9.1(2) and as I was reading the upgrade guide it states "You cannot install upgrade software on your node while the system continues to operate". I have always been able to stage standard upgrades on the inactive partitions of my Publisher and Subscribers without service disruption then switch versions and reboot after hours. I assume that is still the case for standard upgrades within version 9.x, but I figured I would ask the experts for clarification. Can anyone confirm that the 9.1(2) upgrade can be installed on the inactive partition without taking the node out of service.
Thanks in advance,
Dean

Yes, that is still the case. The system will continue to work. The system will not function if you are going from 8.5 or earlier to 9.x where a refresh upgrade is needed.

Hi Dean,
It is a standard upgrade.
When you perform a Refresh Upgrade to the latest release of Cisco Unified Communications Manager,
the system reboots several times as part of the upgrade process, and the service outage period is longer
than with traditional upgrades. Therefore, you may want to perform the upgrade during a scheduled down
time for your organization to avoid service interruptions. (The upgrade is a Refresh Upgrade when the
major OS version changes between the “from” version and “to” version. For Unified Communications
Manager upgrades to 9.1(2), the upgrade executes a Refresh Upgrade when the “from” version is earlier
than Release 8.6(x)).
you can refer release notes.
