They are running a CallManager Pub and Sub, Unity Connection Pub and Presence Pub on one server and a CallManager Sub, Unity Connection Sub and Presence Sub on a second server. They want to upgrade from UC 8.6 to version 10.5 or 11. They are running VMware 5.0.
Will this hardware support this upgrade? From what I have read this server has a restricted performance CPU and it may not support the upgrade. I have reviewed several different support matrices and have not been able to get a clear answer on this.
I'm just about to start an upgrade in the similar setup and am wondering which version you went with and the OVA options. I'm looking at v11 and am trying to figure out of the OVA option for those should be the one that specifies BE6K or the one that specifies the C200.
