[cisco-voip] CUCM Upgrade from 8.6.2 to 8.6.2a su3 -- Advice Request

[Chris Ward (chrward)]

You forgot the upgrade dance and holding your breath!

As a Cisco employee, I have total faith in this upgrade process. :) But seriously, you have the steps correct. And be patient on the reboots. After upgrades, the first reboot takes longer than others, so just bear with it. If you think its hung, just wait longer.

You will need to either allow for phone upgrades (phone may be down during upgrades depending on the model), or you can do them ahead of time with a Device Package. Another thing to add. On your CCX application, the JTAPI version will *may* change in CUCM after the switch version is completed.

CCX will need to be updated:

Subject: [cisco-voip] CUCM Upgrade from 8.6.2 to 8.6.2a su3 -- Advice Request

I am doing my first CUCM upgrade (from version 8.6.2 to 8.6.2a su3) and I wanted a sanity check on my planned process:

  1.  Verify latest backups were successful via Disaster Recovery System / Backup / History
  2.  Insert DVD into Publisher
  3.  Login to CUC OS Administration
  4.  Navigate to Software/Upgrades/Install Upgrade
  5.  Choose the DVD, enter "/" in the directory field, and click next
  6.  Select the upgrade version I am installing (8.6.2a su3)
  7.  Choose "Do not switch to new version after upgrade"
  8.  Click Finish once the install is completed
At that point I will accomplish the same upgrade steps on the Subscriber, again selecting "Do not switch to new version after the upgrade".  Once that system is completed I will use Settings / Version / Switch Version on the Publisher.  From what I read it takes around 15 minutes for the system to stabilize.  Once all of the services are back online on the Publisher I will choose Settings / Version / Switch Version on the Subscriber.

After the Subscriber comes back online I will:


  1.  Verify database replication using Cisco Unified Reporting / Unified CM Database Status Report
  2.  Check to make sure all of my phones, media resources, gateways, CTI devices, and SIP trunks are registered and online
  3.  Make test calls to voicemail, a CCX application, extension to extension, and extension to external to make sure everything is working.
Do you see anything that I am missing and of course thanks for any advice!
