CUCM upgrade from 6.1.1 to 6.1.2

[hauchinango]

I am attempting an upgrade from 6.1.1 to 6.1.2.

I have not found any docs on the procedure, only release notes. Can anybody provide me with the doc or step by step procedure?

Thanks

Step 1 Install the new version of Unified CM on the publisher. Do not reboot.

Step 2 Install the new version of Unified CM on all subscribers simultaneously. Do not reboot.

Step 3 Reboot only the publisher. Switch to the new version of Unified CM and allow some time for the database to initialize.

Step 4 Reboot the TFTP server(s) one at a time. Switch to the new version of Unified CM and wait for the configuration files to be rebuilt before upgrading any further servers in the cluster.

Step 5 Reboot the dedicated music on hold (MoH) server(s) one at a time. Switch to the new version of Unified CM.

Step 6 Reboot the backup subscriber(s) one at a time. Switch to the new version of Unified CM. This step might impact some users if 50/50 load balancing is implemented.

Step 7 Fail-over the devices from the primary subscribers to their backups.

Step 8 Reboot the primary subscriber(s) one at a time. Switch to the new version of Unified CM.

The release notes I believe have how to upgrade it. If not, this is the same basic concept of how to upgrade.

Log into the OS GUI

Click on Software upgrade/install

Select your source/file/login, etc

Click next

it will start the upgrade.

Do this on the PUBLISHER first, after the publisher is done, do the same on the Subscriber. ONe Subscriber at a t time. (thanks rob!)

hope this helps
