CUCM upgrade from 8.5 to 8.6 fails on VMWare.
We have already applied patch ciscocm.refresh_upgrade_v1.1.cop.sgn, and restarted the cluster.
Publisher is upgraded from 8.5 to 8.6. But subscriber upgrade is failed two times.
Is there any other posibilites, why upgrade from 8.5 to 8.6 failing ?
Here I have attached the logs I got during upgrade, two failed upgrade log files attached.
Current version of CUCM-SUB is 188.8.131.5200-26 (running on VMWare)
upgrading to 184.108.40.20600-2
After approx. 90 minutes during upgrade it endup with error.
