-https://techblog.jeppson.org/2016/06/quickly-transfer-vms-xenserver-pools/+Using these commands, VMs are transferred (actually, exported and imported) directly from one 'source pool' member, over a secure SSH connection using the Management network, to a 'destination pool' member. 
 + 
 +This process will **monopolize Management network bandwidth** for a good long while, affecting/affected by all other Management network traffic for the duration of the transfers. 
 + 
 +Exporting, then importing will **flatten (coalesce) all VHD chains** in the process...a wonderful thing.
