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.
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.
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. http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/rel_notes/8_6_1/cucm-rel_notes-861.html#wp1996609
