Migrating WSUS from Server 2003 to Server 2012?


I am sure this topic has been addressed somewhat more than a few times here and on the web.  IE I have googled this stuff before hand, but I am still unclear and or don't like the solutions that I am seeing.

First I will try to describe what I want to do.  I would like to migrate the WSUS role and all of it's approvals and declined updates off of a 2003 Server onto a 2012 Server.  I am aware of the following link http://technet.microsoft.com/en-us/library/hh852339.aspx but this in my opinion is a bit (a lot) ridiculous, way, way too many steps.  It's like something an organization with a dedicated WSUS admin would have the time and focus to do.

Alternatively, I was looking at simply firing up a 2012 server, assigning it the WSUS role and setting it as a downstream update server or whatever the terminology is.  But, I am wondering if this will "downsteam" everything 100% or just the updates downloaded from the upstream WSUS server?  IE I would like it to get all of the historical approvals and declined updates as well as all of the server side targeting setup computer groups and auto approval buckets.  I am worried that it will not capture all of this info and that if I re-pointed our AD GPOs to the new server, shut down the old one and changed the new one to the actual main wsus server as opposed to the downstream on, it would start trying to send out all declined Black Tuesday updates that have plagued this year.  I would like to know what happens in the scenario above.

Thanks for all of your help.

You already have linked to the one and only safe way to migrate WSUS. setting up a downstream server won't preserve what you want and you will have further issues when you shut down the source.

Having done quite a few WSUS migrations, I can honestly say the official process isn't that complicated. It doesn't require a "dedicated" WSUS admin at all, and a general IT Pro should be able to knock it out in a day. Any organization large enough to have (or need) a WSUS specialist is large enough that they've probably outgrown WSUS and are using SCCM/Kace/Shavlik/etc. So the process was written and documented for the jack-of-all-trades type of IT pro. It works. Follow it.
