Move WSUS from Win2008R2 to Win2012R2 without full migration RRS feed

  • Question

  • I am fairly new to network admin and very new to WSUS, so I apologize if I'm asking an old/easy question, but I couldn't find it answered in the forum. I have a Win2008R2 server with WSUS for our domain that has a small 500gb hdd and cannot increase size. Naturally, I have space issues with content folder never having over 5mb. I frequently reset it, but doesn't really help, just fills back up and most of my updates will not sync, so they have to pull them from the internet which defeats the purpose. I have a fresh server with 6tb avail as the content drive. Can I just turn off the old Win2008R2 WSUS services and uninstall it, then install the new WSUS on Win2012R2 and edit the GPO? With the FQDN changed in the GPO, won't the clients all now sync with the new instance? What I've found online says you don't have to do a full-on migration, but don't really give good info on how to do it properly or if there are client changes needed. Any help would be greatly appreciated. Thanks so much.

  • Hello,
    The best practice is forgetting the migration, all your need to do is install the WSUS role on the new 2012 server and modify the GPO to point the clients to the new WSUS. However, there are some things you need to pay attention to.
    1> After you installing WSUS on the 2012 server and before you starting the first synchronization, you should install KB3095113 and KB3159706, and make sure your server is up to date.
    2> If you enable client-side targeting in the GPO, you may need replicate the computer group architecture from the old WSUS to the new WSUS to ensure your clients are displayed in the correct location.
    Hope my answer could help you and look forward to your feedback.
    Best Regards,

  • So I'm going to give you a couple links to my blog articles that may help you with this.

    Second: https://www.ajtek.ca/wsus/how-to-migrate-or-upgrade-wsus/

    As you've mentioned you're new to WSUS, let me also point you to my 8 part blog series on How to Setup, Manage, and Maintain WSUS - https://www.ajtek.ca/wsus/how-to-setup-manage-and-maintain-wsus-part-1-choosing-your-server-os/

    Just as an FYI, following my blog series, my WSUS server's WSUSContent folder fluctuates between 90-120GB for a bunch of products including Office 2013, Windows 7, Windows 10, Server 2012, Server 2012R2, Exchange 2013, and more.
