Not quite the new site will be built and he want to sVmotion the VMDK to the new datastore while leaving the VM running on the host in the original site. Until the application owners are ready to migrate to the new site.This could be up a week later. He then want to shutdown the VM and remove from the inventory on the original vCentre and add it to the inventory on the new vCenter at the new site
I just don't think having a VM running from a different geographical location for up to a week is a great idea as I believe it with impact performance on that VM and I've never really heard of anybody wanting to do it that way. I have suggested using SRM and vsphere replication but he think his way is better?
