Vmware vcenter migration. The operation is not allowed in the current state .

Despite having DRS enabled on our vmware cluster, we are unable to migrate virtual machines.

Every migration ends with the following error:

The operation is not allowed in the current state .
vmware_esx_error_migracion001

Thist issue occurs not only when using powercli, but also when manually trying to migrate:

$vm | move-VM -Datastore  $datastore -Destination $vmhost

If you check the host configuration (summary tab),  vmotion state is set as “No”, though  Host license is Enterprise plus.
