The virtualization wiki has all the info related to products and ESXi versions supported per version, have you reviewed that?

[Gregory Brunn]

Here is a link to the CUCM

https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-cisco-unified-communications-manager.html#v11

Check your version and you can see that you can only be supported with the following esxi version

5.0 U1, 5.1, 5.5, and 6.0

Like java said you will want to check the doc wiki for each product against the esxi version you are going to go to.
