I'm looking at a Qt Extended application built circa 2006-2008 and upgrading to a newer Qt framework. What direction(s) are recommended to upgrade / rewrite this application to get on the latest supported version of some Qt framework?
Is there a recommended path to upgrade from Qt Extended to a newer Qt framework?

I assume this is an embedded platform, and in this is case first of all you need to get Linux BSP with newer Qt version (you can look into Buildroot or Yocto or even a distribution like Debian, all of these have excellent support for Qt), and make sure that you have full HW supported for your platform. This is pretty much platform and product dependent, so i can't really be more specific. After you got the OS up and running, you can start to port your application to port to Qt5. This can be pretty straightforward (see for example https://wiki.qt.io/Transition_from_Qt_4.x_to_Qt5), but can be rather complicated if a lot of Qt Extended related features were used. Again, this depends a lot on the application itself, so hard to give guidelines.
