We have a CallManager 5.1 with more than 500 DLUs, it works fine since few months.
We want to upgrade it to Communications Manager 6.0.1 but we can't find an official migration procedure on Cisco website...
We received an "upgrade 5.x to 6.0" CD which contains a .sgn patch file, and a PAK for generate the Node license.
Via the OS Admin/Upgrade feature of the 5.1, we installed without problem the patch -5to6-.sgn in approximately 1 hour. But after the final reboot and the new license upload, everything seems working except that the CiscoCallManager Service don't run.
In RTMT, we can see a error message "Error - License Validation Failed for SW Version Feature" although the ccm6 license is present and "Used" in Unit Report.
What is the problem?
My questions are :
- Where is the official procedure?
- Why the CCM Service can't run?
Thanks for help!
