I have upgraded the CUCM server from 220.127.116.110-3 to 18.104.22.1680-16. After finishing the upgrade, I am getting the below message on the main web page of the CUCM
Cisco Unified CM Administration
System version: 22.214.171.1240-16
System is operating on Demo licenses. Please upload relevant license files.
Under the license report, the status is demo for CCM Node License Feature.
I have checked all the phones are registered with CUCM, Voice mail, UCCX services are working fine. I do not have any issue.
According to CUCM 6.1.3 release notes, it is an enhancement in licensing which identifies the state of a license.
My question, if it is in demo mode now, will it limited the functionality or CUCM will stop after some time? Or it Is just a warning?
