no logon possible after Windows Server 2022 to 2025 in-place upgrade

After having analyzed the issue for more than 2 weeks I found out that the password of the krbtgt user hadn't been updated for ages (never).Resetting the password before the upgrade did the job. But be careful: if you have more than only one domain controller you should change the password only one time and wait for a very long time (one week!!!) before you upgrade the DC from 2022 to 2025 that everything will be replicated well to the other DCs and also to the member servers/clients.
