Hi,

- To upgrade CUCM from version 11.0 to 11.5(x), you need to go through below upgrade guide:
https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/upgrade/11_5_1/cucm_b_upgrade-guide-cucm-115.html 

- All the prerequisites and upgrade tasks are mentioned in this document.
- Go through the CUCM 11.5 release notes to verify requirements, supported endpoints, limitations etc:

Hi,

after doing a precheck to start the upgrade from cli write :

"utils system upgrade initiate listall"

it will list the source that you can use to download the upgrade patch.
