Hello
- You are correct that Windows Server 2025 CSVLK keys cannot be used on Windows Server 2012 R2. To implement Active Directory-Based Activation (ADBA) for Windows Server 2025, you should use a member server running Windows Server 2025 and install the Volume Activation Services role on it to create the activation object in Active Directory.
- If you use a 2022 CSVLK key for ADBA activation, it will not automatically activate Windows Server 2025. You will need to enter a 2025 CSVLK key to create a new activation object to be able to activate Windows Server 2025.
Have a nice day.
Best Regards,
Hania
