We are planning to upgrade the our cucm 8.0.3 to 9.1.x
Can anyone tell us the steps for the upgradation. We are using the extension mobility. Prior to upgrade we already upgraded the router IOS to c2900-universalk9-mz.SPA.152-4.M5.bin(cisco 2900 series routers). the upgrade on plan on comming weekend
Did you read the 9.1 upgrade guide? I'd suggest starting with it as it is very comprehensive and then les us know if you have further specific questions. You did not state if you are migrating to new hardware as well.
Read the document according to that prepared a document. Could you cross check the document whether i missed any thing to consider the upgradation plan
III. Upgrade considerations
Need to apply the refresh upgrade cop file before doing the actual upgrade for the cucm using 9.1 image.
Sequence for the refresh /upgrade should be
a-Do the refresh upgrade (install the COP file) on the publisher and on the other node( subscriber).
b-Do the upgrade (install the ISO image of the 9.1) on the publisher server then directly do the switch version (utils system switch-version) on the publisher server.
c-Once the switch version is done on the publisher successfully, do the upgrade on the subscriber server and then do a switch version on that subscriber.
B. When we install upgrade software, there will be a temporary node outage while the Cisco Unified Communications Manager software is installed.
C. When we upgrade a cluster we will start by upgrading the publisher node. we can begin upgrading subsequent nodes in parallel after the publisher node reaches a specified point in the upgrade. There will be a temporary node outage until all subscriber nodes get upgraded to the new software version.
d. Disable the Cisco Extension Mobility service by navigating to Cisco Unified Serviceability > Tools > Service Activation
III. Upgrade from CD Rom
Create an upgrade disk by burning the upgrade file that you downloaded onto a DVD as an ISO image.
Insert the new DVD into the disc drive on the local server that is to be upgraded.
Log in to Cisco Unified Communications Operating System Administration.
Navigate to Software Upgrades > Install/Upgrade.
The Software Installation/Upgrade window displays.
From the Source list, choose DVD.
Enter a slash (/) in the Directory field.
To use the Email Notification feature, enter your Email Destination and SMTP Server in the fields provided.
To continue the upgrade process, click Next.
Choose the upgrade version that you want to install and click Next.
In the next window, monitor the progress of the download.
If you want to run the upgraded software at the completion of the upgrade process and automatically reboot to the upgraded partition, choose Switch to new version after upgrade. The system restarts and is running the upgraded software.
If you want to install the upgrade and then manually switch to the upgraded partition at a later time, do the following steps:
•a. Choose Do not switch to new version after upgrade.
•b. Click Next
The Upgrade Status window displays the Upgrade log.
•c. When the installation completes, click Finish.
•d. To restart the system and activate the upgrade, choose Settings > Version; then, click Switch Version.
The system restarts running the upgraded software.
IV. Post-upgrade tasks
•a. Enable the Cisco Extension Mobility service by navigating to Cisco Unified Serviceability > Tools > Service Activation.
•b. Verify phone functions by making the following types of calls:
Since you are going to version 9 don't forget about new licensing model and conversion to ELM, ensure you have everything ready for that including registered all PAKs, owner ID associated to devices, and ensure you perform the license migration in ELM.
