is it possible to update windows server 2022 RTM to build 25977 ?

without losing activation and original serial and without the need to enter a new serial ?

or is it impossible to install a preview on a regular RTM server as a regular upgrade ?

and how to do that then ?

I don't see how, it's a different product and the keys are different. 25977 is Server vNext, where vNext will likely turn into 2024 or 2025 closer to release.

Can you explain a little more on what you're trying to do? Regardless, you can always install the Hyper-V features and use 25977 in a virtual machine to avoid having to upgrade.

Also in case you missed it, in the known issues for 25977 and other recent builds, there are a few known issues when upgrading from 2019 or 2022, although those might not matter in your scenario.
Windows Server vNext setup, because it is still branded as Windows Server 2022, continues to accept Server 2022 keys for the time being.
