[cisco-voip] changing vCPU count in cluster

[Ryan Huff]

5 node 10.5.2 ccm cluster, each node based on the 2,500 user OVA

The OVA deploys with one vCPU however, the docwiki (http://docwiki.cisco.com/wiki/Virtualization_for_Cisco_Unified_Communications_Manager_(CUCM)#Notes_on_2500_user_VM_configurations)
 
Shows that it may be advisable to deploy with 2 vCPU on the VM. 
 
So my question is that in my running 5 node cluster; what would be the best way to do that? Power off one VM at a time, add the vCPU and then power back on? Should I do the pub first .... etc?
 
Thanks,

Ryan
