<![CDATA[I have an issue after updating Qt from 5.14 to 6.3.0-rc in the compiler]]>The compiler used originaly was MSVC 2017-64 bit, the one used in Qt is MSVC 2019-64 bit. This "migration" has produced numerous errors that I honestly don't understand where they're coming from or what triggered them.

Thing is I don't know if I did something wrong when upgrading or if there is something missing. So what does someone typically do when they have a project and want to update Qt to a higher version to have access to the latest tools? I mean these errors weren't present before so what exactly triggered them?

Most people report that the porting effort was small, but that of course depends a lot on your code base ...

Feel free to reach out here though if you have issues with specific cases!

like QStribg with the new ones that were made for Qt 6, correct?

I don't know what QStrigb is but yes - replace the deprecated functions with the correct ones.
You should have done this before upgrading to Qt6 though - Qt5.15 issued a warning for every deprecated function.

For the rest - add the appropriate includes.
See e.g. TextColorRole or qsrand().
