Hi,
I'm assuming this is not a vCloud Director Environment.If it is a vSphere Environment integrated with vShield Manager and 1000v,you can certainly go to edge settings by logging into vShield Manager GUI and change the respective interface to new DVS.
Log-into vShield Manager GUI.
Select Inventory > Hosts & Clusters> Select a datacenter resource from the inventory panel > Click the Network Virtualization tab. >Click the Edges link. > Double-click a vShield Edge. >Click the Configure tab. > Click the Interfaces link>change the respective interface to new DVS Portgroup.
