Can't apply vSphere Standard license on ESXi hosts if they are using DVS even if you have a NSX-T License

Products

• VMware NSX

Issue/Introduction

Symptoms:
Whenever you try to apply a vSphere Standard license on a ESXI host that is using a VDS you get the following : 

#The selected license does not include the vSphere Distributed Switch feature.

This should be possible according to this doc : 
https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.1/administration/GUID-065D6BE8-1E72-48EB-BD2C-821FA86E1142.html

If you have an NSX-T license, you do not need an Enterprise Plus license for VDS.

Environment

VMware NSX-T Data Center

Resolution

No resolution for now

Workaround:

1. Put the host into Maintenance Mode
2. Migrate Management VMK / physical NICs to a Standard Switch
3. Detach the host from all the DVSs 
4. Apply the license to the host
5. Re-attach the host to the DVSs and migrate VMK / physical NICs to the DVSs 
6. Exit Maintenance Mode
