What do you mean by DC’s? By what you wrote I guess that you’re not referring to what would typically be considered a Data Centre. If all you want to do is to move a VM from one ESXi host to another then use vMotion. If you’re looking to do something else please get back with a clarification on what it is that you want to accomplish.
In my view a data centre is a collection of ESXi hosts in a ESXi system at one location, that is not the same as two different hosts in a ESXi system within a data centre. It is absolutely possible to move VMs between two different data centres with vMotion, but that typically also includes various other things like change of IP address on the service that is running on the VM.
That is a very big and quite complicated thing to do and involves a long list of activities that you need to complete. For one it very likely involves a change of IP address of the service running on the VM that you plan to move.
