Can Windows Server 2012 Be Upgraded To 2022?

No, You can't directly upgrade from Windows Server 2012 to 2022; you must first upgrade to Windows Server 2016 or 2019, then upgrade to 2022.

Here's a more detailed explanation:

No Direct Upgrade:
Microsoft doesn't support a direct in-place upgrade from Windows Server 2012 to Windows Server 2022. 

Two-Step Process:
You need to perform a two-step upgrade: first, upgrade to either Windows Server 2016 or 2019, and then upgrade to Windows Server 2022.

Why not direct upgrade?
The differences in the underlying architecture and components between Windows Server 2012 and 2022 are too significant to allow a direct upgrade. 
Considerations for Upgrade.

In-place Upgrade:While an in-place upgrade is possible, it's generally recommended to perform a clean install or migration for optimal performance and stability.

Backups: Always back up your system and data before performing any major upgrades or migrations. 
Application Compatibility: Ensure that all applications and software are compatible with the new Windows Server version. 
Domain Controllers: If you're upgrading a domain controller, plan for a new domain controller and migrate the roles to the new server. 

Services: Ensure that all services running on the server are compatible with the new version. 

Drivers: Check for any incompatible drivers, especially for older printers. 
Legacy Applications: Be aware that non-Microsoft legacy applications might require updates or replacements.

End of Life:
Microsoft's blog states that Windows Server 2012 and 2012 R2 reached their end of life on October 10, 2023.
