If you are running an older version of CUCM and want to upgrade to the latest release, you will need to download the CUCM ISO file from the Cisco website or other sources. This file is a bootable image that contains the CUCM software and the necessary scripts to perform the upgrade.

Before you start the upgrade process, you should make sure that you have a valid ESW contract and UCSS for major upgrades, as well as a backup of your current configuration and data. You should also check the compatibility matrix and the upgrade guide for any prerequisites and recommendations.

To upgrade to CUCM, you will need to follow these steps:

  • Burn the ISO file to a DVD or copy it to a USB drive formatted with the Microsoft FAT32 file system.

  • Insert the DVD or USB drive into the server that runs CUCM.

  • Reboot the server and press F6 to boot from the DVD or USB drive.

  • Follow the prompts on the screen to start the upgrade process.

  • Select the option to install or upgrade CUCM.

  • Enter your credentials and accept the license agreement.

  • Select the option to refresh upgrade and choose the CUCM file from the DVD or USB drive.

  • Wait for the upgrade process to complete, which may take several hours depending on your system configuration and network speed.

  • Reboot the server and verify that CUCM is running properly.

Congratulations! You have successfully upgraded to CUCM ISO 4.56 GB.
