Hello Dinesh Kumar Vaishya,
Thank you for posting in Q&A forum.
Here are some additional steps you can try to resolve this issue:
- Make sure there is enough free disk space on the server. Insufficient disk space can cause the upgrade to fail.
- Temporarily disable any antivirus or security software during the upgrade process, as these can sometimes interfere with the installation.
- Ensure that the server's BIOS and firmware are up to date. Outdated firmware can cause compatibility issues during the upgrade.
4.Make sure there are no pending updates on the current Windows Server 2012 installation. Install all available updates before attempting the upgrade again.
- Review Setup Logs
Check the setup logs for any specific errors that might indicate the cause of the issue. The logs can be found in the following locations:
• C:$WINDOWS.~BT\Sources\Panther\setuperr.log
• C:$WINDOWS.~BT\Sources\Panther\setupact.log
- Consider a Two-Step Upgrade
If the direct upgrade from 2012 to 2019 continues to fail, consider upgrading to Windows Server 2016 first, and then from 2016 to 2019. This two-step process can sometimes resolve compatibility issues.
Reference:
In-place upgrade 2012 to 2019 - Windows - Spiceworks Community
In-place upgrade 2012 to 2019 - Windows - Spiceworks Community
I hope the information above is helpful.
