> Well if you were using modules that are no longer supported, or you run into some little incompatibility; but we have been trying to avoid API breaks.  QML files that begin with “import QtQuick 2.0” still work fine so far; also Controls, Layouts etc.  So IMO it’s less onerous than the python upgrade.I *think* that in this point we are talking about plugins within QML modules. Can a Qt6 QML module be used in a Qt 5 application or the other way around? I think the answer is no. And if the answer is no you need to be able to co install this two different versions.
