I have an old Windows 8 running BI4 for long time. Now I have a new Windows 11 to replace the old PC and would like to upgrade to BI6 with AI.
I planned to install BI4 on new Windows 11 PC, activate license and purchase extended maintenance license, then upgrade to BI6. However, it failed to install BI4 on Windows 11. I got following error when running BI4 on Windows 11. That didn't work.

How I can migrate both license and backup from BI4 to BI6? Need some help and instructions here.
