Hi everyone,
I am in the process of upgrading 3x UC applications - UCM/CUC/CER to version 12.5 and I've run into a critical issue.
The upgrade seems to be proceeding just fine, the system reboots, installs a bunch of stuff, then when it reboots again, you can briefly see the CentOS screen flash and then it just goes to a black window with a bar. Please see attached.
The upgrade is from the latest version of 11.5 to the latest version of 12.5.
I have verified that the VM settings are correct - updated to latest version of VMware, CentOS 64, correct network adapter.
I have attempted the process twice and it does the same exact thing both times. The screen goes blank and all CPU/disk activity stops.
My next option would be a PCD Migration, but that doesn't help me with CER.
Any thoughts?
