Multiple vsan datastores in a single datacenter?

I currently have 7 esxi 6.0u3 hosts (HCI) running vsan 6.2 in a vspehre 6.7 (with external PSCs) datacenter cluster.

I have built 6 new hosts with esxi 6.7, and plan to migrate all our VMs from the 6.0U3 stack to the 6.7 stack.

Is it possible to add the 6 new hosts to a new cluster under the same datacenter as the 6.0u3 cluster, and create a vsan 6.6.1 datastore in the new cluster?

It would roughly look like this:

DatacenterA

--ClusterA(6.0U3)

----VsanDatastoreA(6.2)

--ClusterB(6.7)

----VsanDatastoreB(6.6.1)

The goal would be to vmotion the VMs from VsanDatastoreA to VsanDatastoreB.

Possible?

Thanks!
