vMotion across datacenters within same vCenter

Hi All,

I have 1 vCenter server running 6.7 managing 2 separate datacenters, each running hosts with ESXi 6.7. Each datacenter is located in a different physical location and there is no layer 2 connectivity between them.

I need to hot-migrate the VM's from one datacenter to the other and need to make sure I have the proper network configuration to make that happen. We are changing the IP address of the VM's once the VM is migrated to the new location.

My question is:
Do the vMotion networks need to be routable? So if the IP for a host in datacenter 1 is 192.168.2.2 and the IP for a host in datacenter 2 is 10.8.2.3, does the vmknic on the datacenter 1 host need to be able to route to the vmknic on the datacenter 2 host?  Or does it not have to have layer 3 since they are all sitting under the same vCenter server?
*Note that the management networks are already routable, just not the vmotion networks at this time.

Thanks!
