How do I migrate an ESXi host from a vDS to a vSwitch with NAS storage on the vDS

I need to move some esxi hosts off a vDS to a standard vSwitch in preparation for moving the ESXi hosts to a new vCenter

I have two 10 GB NICs that handle VM ports, NAS storage, and vmotion.

Is there a documented procedure for moving from a vDS to a vSwitch, particularly for migrating the NAS storage to a vSwitch?

Thanks

Tom
