Question about CCM Upgrade from 8.0 to 8.6

Hi,

I have a quick confirmation question.

We currently have a CUCM 8.0 cluster installed as virtual machines on Cisco UCS hardware.

I will be doing an upgrade to 8.6 soon.  I know that the upgrade patch is needed first.

I don't think we need to get any new licenses (e.g. SW feature license) since we are upgrading within the 8.0 family.  Is that correct?

Besides the licensing is there anything else I'm missing or should be aware of?

Also can I install 8.6 into the inactive partition and load to that version at a later time?  I don't think I can, but I wanted to check.

Thank you!

Hi Rya,

It sounds like you've done your homework here Just a couple of notes

from this end;

- your Software Feature License will carry forward so you're good to go

- the "''Refresh Upgrade" is quite different and you are most correct on

the switch-version later query. There will be an outage regardless.

Overview of the Software Upgrade Process

With this version of Cisco Unified Communications Manager, you cannot install upgrade software on your server while the system continues to operate.


Caution If  you are upgrading your software on HP 7825H3 or HP7828H3 hardware,  there is no option to revert to the previous version of Cisco Unified  Communications Manager. To perform an upgrade on one of these machines  you must use a 16GB USB device to facilitate data migration from the old  system to the new installation. For Unity Connection and Business  Edition 5000, a 128GB external USB device is required.


When  you install 8.6 upgrade software, there will be a temporary server  outage while the CUCM software is installed. Once you kick off the  upgrade using either the command line or graphical user interface the  data will be exported, and the system will be automatically rebooted at  which point the server outage will begin. The duration of this outage  will depend on your configuration and amount of data. During the  upgrade, progress can be monitored via the console until such time that  command line interface and graphical user interface access has been  restored. Once restored, you can use the command line interface or  graphical user interface to continue to monitor upgrade progress.


Note If  an administrator or a phone user makes changes during the upgrade  process (export of data), that data could be lost after upgrade.


When  you initiate the upgrade, you can indicate to activate the partition  with the new upgrade software or return to using the partition with the  previous version of the software at upgrade completion. With the  exception of HP 7825H3 and HP7828H3 hardware upgrades, the previous  software remains in the inactive partition until the next upgrade. Your  configuration information migrates automatically to the upgraded version  in the active partition.

When  you upgrade a cluster, you start by upgrading the first node. Once the  upgrade on the first node completes, you can begin upgrading subsequent  nodes in parallel.

All  servers in a cluster must run the same release of Cisco Unified  Communications Manager. The only exception is during a cluster software  upgrade, during which a temporary mismatch is allowed.

If  for any reason you decide to back out of the upgrade, you can restart  the system to the inactive partition that contains the older version of  the software. However, any configuration changes that you made since you  upgraded the software will get lost.


Note You  can only make changes to the database on the active partition. The  database on the inactive partition does not get updated. If you make  changes to the database after an upgrade, you must repeat those changes  after switching the partition.


If  the upgrade of a subsequent node fails after you upgrade the first node  and switch it to the new version or fail to upgrade one of the  subsequent nodes in your cluster during the upgrade cycle, you can do  one of the following:

Correct  the errors that caused the upgrade failure on the subsequent node. You  may want to check the network connectivity of the nodes in your cluster,  reboot the subsequent node, ensure the server memory and CPU usage on  the subsequent node is not too high. Upgrade the subsequent node again.

Make  sure that the active partition of the first node runs the newest  version of software installed on the server. Perform a fresh  installation on the subsequent node using the same software version as  that running on the active partition of the first node. If you are  reinstalling the subsequent node, you should delete the server from  Cisco Unified Communications Manager Administration and add the server  again as described in the Cisco Unified Communications Manager Administration Guide.

You  can upgrade from a DVD (local source) or from a network location (remote  source) that the Cisco Unified Communications Manager server can access.

For a  short period of time after you install Cisco Unified Communications  Manager or switch over after upgrading to a different product version,  settings changes made by phone users might get unset. Examples of phone  user settings include call forwarding and message waiting indication  light settings. This can occur because Cisco Unified Communications  Manager synchronizes the database after an installation or upgrade,  which can overwrite phone user settings changes.


Caution Be sure to back up your system data before starting the software upgrade process. For more information, see the Disaster Recovery System Administration Guide.  If you are upgrading your software on HP 7825H3 or HP7828H3 hardware,  there is no option to revert to the previous version of Cisco Unified  Communications Manager. If you do not back up your system data before  starting the software upgrade process your data will be lost if your  upgrade fails for some reason. If you chose to revert to the prior  version, you will need to install the prior version and restore your  data from your DRS backup.
