If I already have User CALs that came with licensing a server, then if I'm updating a different server's core licensing will I need new User CALs for people to access the server being updated?

Question

Hello all,

If I already have User CALs that came with licensing a server (server1), then if I'm updating a different server's (server2) core licensing will I need new User CALs for people to access the server (server2) being updated?

I understand that CALs are required to access the network.. if I have 1 physical server of 6 that has 50 user CALs, wouldn't that be all the CALs I need total for all of the servers for my entire network?

Thank you

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)
