I'm using VMware vCenter Server Appliance 6.7.0.42000 Build number 15132721
I get the error Invalid datastore path '[datastore.251] Server2/Server2.vmdk' when cloning a VM from a VMware ESXi 6.7.0 8169922 to a VMware ESXi, 6.7.0 14320388
But I get the same error in other three cases with other vCenter and Esxi environments (also previous builds).
The only common thing is that the cloned vm has more than one hard disk.
Thanks
