Working on a Qt3 to Qt4 port we are noticing that QSettings loses the users setting from Qt3. In addition the file format is changed and the Qt4 QSettings system ignores the Qt3 configuration settings even if the Qt3 ini file is moved to the new Qt4 location and renamed to have the default Qt4 file name.

This has to be an issue for other projects and I would like to know how others are handling it. I have done searches here and on the net and have not found anything about this.
