XPS 8950, Windows 21H2 to 22H2 upgrade?

Hi,

Has anyone performed the upgrade from Windows 11 21H2 to 22H2 on XPS 8950 desktop? Any issues? Does it allow rollback to previous version?

According to this, Dell has tested XPS 8950 desktop for Windows 11 22H2. I don't know what that really means? Will the upgrade mess up anything (from the interface to restore point creation, scheduled task, personal settings,  drivers, etc) ?

Dell computers tested for update to Windows 11 build 22H2 and previous versions of Windows 11
