Yes, with the caveat that any changes you did on 11.5 will be lost.

Start by looking at the compatibility info of each product in the target release to determine if you need to do it in a certain order, the CUCM upgrade guide contains upgrade paths and provides estimates for various upgrade options.

Jamie,
If we upgrade UCM 10.5 to 11.5 and switch version to 11.5
when we see some issue, can we always go back to 10.5 ( switch version) and no problem ?

do we need to worry on ITL or certs on 11.5 when we switch back to 10.5?

Certificates are handled at OS level.

so you mean switch back and forth partition between UCM 10.5 and 11.5 not an issue ?
