vDS configuation lost when switching from eval to Standard license?

Hello,

My question is:

If I change my license from evaluation to Standard, will I lose my virtual distributed switch configuration?

Details:

I have 3 ESXi hosts and have configured a vDS used by all 3 hosts.

I’m using an evaluation license for vSphere 5.1 and have purchased the 5.1 Standard License.

I understand that the Standard license does not support vDS.  Does this mean that when I apply the Standard License I will lose my network configuration?

Thank you in advance.
