WSUS Migration: Existing self-signed certificate becomes invalide

Topics: Configuration Issue
Feb 11, 2015 at 10:54 PM
Hello everyone,

after migrating (replication) the exisiting WSUS-Server (2003 R2) to a new server (2008 R2) WPP reports that the is any certificate.
The former certificate was succesfully imported to the new WSUS-Server (Trusted Root Certificates, Trusted Publishers and WSUS) and the WSUS service was restarted.

But WPP still asks for a new certificate. After creating a new certificate WPP starts without error but the 3-party-Updates can not imported/resigned.

So we used both certificates (old and new), imported the 3-party-updates and resigned them. After that we dropped the old certificate.

Is there any other options when migrating WSUS to a new machine?

Best regards
Server 2003 R2 Standard
WSUS 3.2.7600.274
WPP 1.3.1411.9

Server 2008 R2 Standard
WSUS 3.2.7600.251
WPP 1.3.1411.9

In WSUS-FAQ No. 44 you will find needed Updates for your new WSUS:

WSUS 3.0 (SP2): Build 3.2.7600.226
WSUS 3.0 (SP2) + KB2720211: Build 3.2.7600.251
WSUS 3.0 (SP2) + KB2734608: Build 3.2.7600.256
WSUS 3.0 (SP2) + KB2828185: Build 3.2.7600.262
WSUS 3.0 (SP2) + KB2938066: Build 3.2.7600.274

Update your WSUS first, reboot after the last patch and try it again.

Hello WinfriedSonntag,

thanks for Your quick reply!

Unfortunately the migration is done so we can not test Your suggestion. So I hope that someone else found this BEFORE migrating.

When you need to import a new certificate, it's not enought to put the certificate in the right cert stores. You have to use the option "Import a certificate" in WPP. If you don't use this option, Wsus will not use the cert.

If you use a self-signed cert, this cert is tight to the server and can not be use by another server.

Hello DCourtel,

thanks for Your reply.

You are right because the certificate is self-signed. Ok, I keep that in my mind when migrating WSUS again.
