Re: Upgrade Instructions of Unified Communications Manager 6.0(1
-At this point we are ready to upgrade our Cisco Unified Communications Manager Servers. Of coure I highly recommend you to back up your UCM configurations first.
We will start first with our Publisher Server.
Please visit the Cisco Unified CM Administration page of the publisher.
Navigate to the Cisco Unifed OS Administration
-Proceed to login
-Select the Software Upgrade Tab
-Select the Install/Upgrade Tab
-Insert DVD on the publisher.
-Under Software location select DVD
-Under Directory Enter the path location of the our ISO file which in our case should be
-In this screen you will have the option to either select to "auto reboot after the upgrade is complete" or "not to reboot the server after the upgrade process has been complete".
-In our case we wanted to minimize our downtime window as well we had an outage window of approx 15 minutes. Meaning that when the upgrade process was running in both servers while our UCM cluster was operational all we had to do once the upgrade proccess was completed succesfully was only to reboot our UCM servers accordinally.
-If you choose to auto reboot after the upgrade process was completed then the servers will reboot after the process is completed
-After aproximately 15 to 20 minutes the DVD will eject automatically(although the upgrade process will continue) in which time you can proceed to use the DVD to start the upgrade process in your Subscriber.
-UCM will print a message on your screen stating that the upgrade process status is now complete.
-SSH to the publisher, login and enter the following command
admin: show version active
this command will show you the current active version running in your UCM
admin:show version inactive
this command will show you the version of UCM running in the inactive partition
which now that the upgrade process has been completed it should be
Inactive Master Version: 126.96.36.1990-13
After that you have indeed verified the active and inactive versions of UCM procceed to the next step.
-In my case I had a cluster of 2 UCM servers a PUB and a SUB
To minimize risks I waited for the SUB upgrade process to finish. Once the SUB upgrade process was completed I SSH to the Sub and verify the versions using the same commmands.
I then proceeded to connect my KVM to the Sub server and I unplug the network cable.
-On the Pub Using the SSH console I proceeded to issue the following command
admin :utils system switch-version
-It will take approx 3 to 6 minutes for the Pub Server to auto restart, The pub server should now boot using the new version.
-Once the Publisher server has fully complete the Boot process, Using a KVM that was plugged to the Sub server I procceeded to enter the following command.
admin:utils system switch-version
This command will have the same effect as on our Publisher server.
The subcriber server should now boot using the new Cisco Unified Communications version.
