r/sysadmin on Reddit: 2012 Extended Support Cost
8 May 2023 -

Was curious if anybody had a ballpark estimate of what a 16 Core pack of Server 2012 standard would cost? We use volume licensing and and am trying to prepare our client for what the total cost is going to be to continue to patch these servers that they can't afford to upgrade.

r/sysadmin on Reddit: Does Windows Server 2012 extended support (the period up to Oct 10 2023) cost additional licensing fees?
7 December 2018 -

Hello experts, I'm asking this question because I'm on the application development and support side of things for a large company and my infrastructure coordinator, who is a total bozo, is insisting I can only have Windows Server 2016 or 2019 servers built, because Windows Server 2012 is out of support, and it would be expensive to pay for extended support. After 5 minutes of Googling this subject, I can find nowhere that states the extended support period that lasts until October 10 2023 will be an additional cost. And yes, we will definitely undertake a project in Q4 of 2022 to migrate our 5 dozen 2012 servers to whatever the newest version is, but we do not want to be forced off of 2012 right now.

It’s my understanding that you should be able to buy the ESUs from any Microsoft CSP. The MAK will show up in the MAC (admin.microsoft.com), which you’ll add to each server using slmgr.vbs /ipk and then activate.

You’ll typically get 3 years of updates via ESU. Each license is only valid for a year, so you’ll need to re-license each server annually. In my experience, the cost per license doubles each year.

If you’re interested in getting in contact with someone who can sell you ESUs, send me a DM. They’re located locally to me (MN). I’m not sure if they’re able to sell to companies in other states, as they’re mostly a local MSP/ITSP, but it’d be worth asking.

We have a client that’s got a Windows Server 2012 R2 server and a pretty extensive Autodesk Revit deployment with Revit Servers 2018 through 2024. Their projects are typically very large and long running so there are still projects in Revit 2018 that are being actively worked on. We started working back in September of last year to try to migrate them to at least Revit 2021 (which supports Windows Server 2022) but we aren’t going to make it and they’re likely going to be stuck on Windows Server 2012 for quite a while. At this point, we have to start looking at how to keep the Server 2012 going for as long as we can and the Extended Security Updates seem to be our only option. We usually buy Microsoft licensing through TechData / TD Synnex but they have basically said “we don’t do that” and hung up. I’m digging around on the Microsoft site now to try to wrap my head around it but am not making a lot of progress. Can anyone here give me some pointers or point me in the right direction on this? My original hope was that there would just be a SKU that I’d buy that would give me a magical key or something to continue getting updates but that’s apparently not the case
