Windows Server CALs
Windows Server CALs
Hey there,
I see you're dealing with an upgrade from Windows Server 2012 R2 Essential to Standard. Since you can't purchase the user CALs for R2, it looks like you might need to use Windows Server 2016 CALs instead. They should be compatible with the downgrade process. Let me know if you want more details!
Discuss your licensing needs with a Windows expert. There are various CAL types, many not sold directly to consumers. You’ll usually need to purchase from an authorized enterprise reseller handling Microsoft products. Some sites like NewEgg may carry newer CALs, but older versions might be missing. In theory, you can downgrade from 2016 CALs, but this requires contacting a specific Microsoft department—see the reference link provided. The advice is to speak directly with a Microsoft Reseller and get the appropriate CAL for your Windows version from the start.
