Restoring dvSwitch Configuration

Hi,

I have a vCenter Server that I rebuilt from scratch again because it crashes few days ago due to the database being full. I didn't bother to backup the dvSwitch configuration before re-installing the vCenter Server.

Now the newly built vCenter Server is up and running but when I added the ESXi hosts the dvSwitch is gone for all of them. When I logged in to each ESXi hosts directly using the vSphere client, the dvSwitch is there and perfectly fine and in fact I can still connect to all my VM's.

Now my question is, is there a way I can import the dvSwitch Configuration from each hosts to the vCenter Server? The dvSwitch configuration is there, it's just not showing in vCenter Server.

Thanks for any help!!
