I read that CUCM upgrade from 8.6 to 9.x was supported as a direct upgade so I upgraded a CUCM cluster from 8.6.2 to 9.1.1. The 8.6.2 CUCM cluster (14 VM) is running in virtualized environment (4 C210 servers, esxi 5). The VM for every CUCM server has 2 vCPU, 2 80GB vDisks and 6 GB RAM. After the upgrade the CUCM Cluster is running 9.1.1. in active partition with 8.6.2 in inactive partition. I didn´t modify the VM for the servers, so the server with 9.1.1 are using the same value 2 vCPU, 2 80GB vDisks and 6 GB RAM (7500 users). I read that the VM for a fresh install of 9.1.1 require 2vCPU, 1 110GB vDisk and 6 GB RAM (for 7500 users). Can the diference in vDisks affect the performance of the CUCM in any way? Should I just modify the value in the VM to provision 110 GB to vDisk 1, and left 80 GB in vDisk 2.
