Qt5 to Qt6 is nothing like Python2 to Python3. The lessons from (Qt3 to Qt4 and) Qt4 to Qt5 have been learned and moving a large project from Qt5 to Qt6 is not that hard comparatively. There are a few minor deprecated APIs to handle and it's relatively easy over all. I even have a stable project that is compatible with Qt5 and Qt6 [1] all in a single code base (particularly thanks to the effort of the qtpy[2] library). It's not that hard, and my opinion includes C++ in that assessment.
