Wsus 3.2 on Server 2008 R2’s end of life has been extended until 2020, keep in mind though if you are (or are planning) servicing Windows 10 you should plan moving to Wsus 4 asap, Wsus 3.2 can’t service Windows 10 upgrades (feature updates) and will not get this feature.
As you may have seen, there has been an update to the extended support lifecycle for WSUS 3.0 SP2 (WSUS 3.2). We received feedback that ending this product’s life in July 2017 would cause a significant disruption for those Windows Server 2008/R2 deployments that planned to rely upon it until January 2020. As such, the end of life for this product is now January 2020.
For those that currently rely on WSUS 3.2, please use this extension as an opportunity to plan a smooth transition to WSUS 4.0 (Windows Server 2012 or 2012 R2) or even our newest offering (Windows Server 2016) that will be available later this year. Especially for larger businesses, migrating a WSUS hierarchy is nontrivial, and may take much of the extra time that has been granted for this operation. We’ve assembled a collection of resources that will help inform your migration efforts; should you have any trouble with the process, feel free to reach out on our TechNet forum for assistance.
Finally, it bears repeating: if you plan to deploy Windows 10 your environment, yet are still using WSUS 3.2, then we strongly recommend considering a migration sooner rather than later. WSUS 3.2 cannot today and will not in the future be able to fully support Windows 10 servicing (specifically feature updates), and in order to experience the true vision for Windows as a service, you’ll need to use WSUS 4.0 or later.
