I have an existing environment :
CUCM : 18.104.22.16800-2
CXX : 22.214.171.12400-37
I want to upgrade my existing CUCM to version 10.5. Is CUCM 10.5 still can integrate with my existing CCX version ? or I also must upgrade my CCX to 10.5 ?
Because in compatibilty matrix document ,only CCX version 8 that can integrate with version 8 too. Below my reference document :
Need your advice to solve my issue, Thank You.
No, they don't include later versions like 9.x or 10.x.
I have a bad experience of customers risking unsupported upgrades and then trying to force me to solve the situation. If it's unsupported, then it's unsupported, no exceptions.
