Viprion without vCMP to Viprion with vCMP

You will need to configure manually the host and guests. As you already said, some configuration will go to the host and other to the guests.

After that, you can load some part of the configuration.

Use either the UCS or SCF to cut the shared configuration (like vs/pools/etc...), then use the merge command to load that.

tmsh load sys config merge 
tmsh save sys config partitions all
