New WSUS Build

My current WSUS environment has been running for about 6 years and is almost completely useless at this point. W3WP.exe and SQLSERVR.exe memory and CPU usage are through the roof. Clients have to check multiple times because of timeouts and this has become a huge issue. I have run all the cleanup scripts and installed recommended WSUS patches and still poor performance. I have now setup a new server and right now it's getting the metadata from Microsoft. I'm 66% through and right now it is showing 11,000 updates. I've chosen all classifications except for drivers. This will take forever to download. Is there a way to point the new WSUS server at the existing WSUS server, that is local, and then switch it back to Microsoft after the downloads are complete? There are a few categories that are enabled on the new one that are not enabled on the old one but I can sync those from Microsoft later. Downloads will be a lot quicker from a local server. Thanks.

You can export from your current and import to the new, but honestly, if your old is that messed up might be safer to just wait till it finishes.

WSUS will not download any updates unless they are approved.  You are better off approving only needed updates.

You can synchronize with Microsoft or local upstream WSUS server.

11,000 updates ??? I would only approve "Needed" updates to start with.

You can configure the new one as a downstream of the existing one and let it sync. once sync completes, configure it to point to Microsoft for getting new updates.
Daryl BamforthTechnical ExpertCommented:
To connect a downstream server to an upstream server:
In the left pane of the WSUS Administration console, click Options.
Select the Update Source and Proxy Server option and click the Update Source tab.
Select the Synchronize from another Windows Server Update Services server check box, and then type the server name and port number in the corresponding boxes.
If you are planning to use SSL for this connection, select the Use SSL when synchronizing update information check box. The port used for this connection will be 443.
If you want this server to be a replica of the upstream server, select the This server is a replica of the upstream server check box.
Click OK.
