Hi Experts,
I'm in the process of doing the upgrade or migration from CUCM BE v6.1 to CUCM v8.6 and UC 8.6 on UCS but I'd like to know if there are some guides or documents to help smoothing the process.
I found some documents on doing the upgrade from old regular edition version (like 6.0) to the same regular edition but new version (v8.6) but didn't find how to do it from BE to CM.
Thanks for your inputs in advance.
Regards.
Khaled
