Migrating WSUS from one drive to another - Server 2008 R2

The drive on one of our DC's is full. The WSUS is sitting on this server.

I provisioned a new HDD and added it to the server. I now want to migrate the WSUS data on to the new drive.

Has anyone actually doe this before?

I found this on the web. Does it look correct?

If you can, I would be looking to move it to a server that's not a DC.
