My vCenter 5.5 connects to a few hosts. I am in the middle of upgrade the version from 5.5 to 6.
I setup a new vm and install vCenter 6 and also setup update manager. I have removed a host (in maintenance mode) from the current vCenter 5.5 and add it to vCenter 6 and upgraded the host to version 6 using update manager.
I am ready to remove the next host from my vCenter 5.5. However, this host has a couple of important VMs in it. Without putting it in maintenance mode or shutting down any VM, is there a way to add this next host to be upgraded into the vCenter 6 so I can perform the upgrade?
