Can I use Windows Server 2016 User CALs for Windows Server 2019?

Question

We are planning to upgrade from Windows Server 2016 to Windows Server 2019. Can we use Windows Server 2016 User CALs for Windows Server 2019?

Another way I can put it: Are Windows Server 2016 User CALs forwards compatible?

Thank you in advance!

Answer 1

A Windows Server CAL is a license that grants access Windows Server. CALs are used in conjunction with Microsoft Windows Server OS licenses to allow Users and/or Devices to access and utilize the services of that windows server

• User CALs allow a single user access to Windows Server from an unlimited number of devices
• Device CALs allow an unlimited number of users to access Windows Server from a single device
• CALs are licensed to access servers of the same level and below. (not forward compatible)
