Windows Server 2022

Pros

• Honestly as long as you migrate the FSMO roles and have at least 3 total DCs, you can usually do in place upgrades by now. Should something go wrong you still have a safety factor while standing up a new one.
• I googled the steps and cleanly migrated from 2012 r2 to 2022. I did add a new 2022 dc virtual machine to start the AD upgrade.
• Create new VM with Server 2022 Standard, do not use 2025 at this time as there are many known issues
• Frankly though, do not use 2025 for AD at all for the medium term: stick to 2022.
• 2022 if you want stable.

Cons

• We had to upgrade to 2022 because 2016 was EOL soon and Teams was not supported, etc. And we ran into similar issues. 2022 performance was worse.
• we are able to boot the OS but it loade automatic repair and then BSOD with error "**Driver Verifier DMA Violation"** and reboot and bootlooping**.
• Windows Server 2022 did improve a lot of things, but there’s simply no trust left in the Windows Server team.
• If you go for 2022 you'll need to follow the upgrade path in steps one at a time.
• We migrate to 2022 for now, but you have to do it in steps, i.e 2012 > 2016 > 2019 > 2022. I actually had to revert a snapshot for some servers because the in place upgrade broke the services, so please have a backup plan.
