In addition to what @bernd_lu has said, there are also a few topics in the Clarion help file that might be (mildly) useful.
- Converting Applications from Clarion 6
- Resolving Application Conversion Issues
- Converting Topspeed Project Files to MSBuild projects
There is also the “What’s new in this Version?” section at the bottom of the online help contents list. Screenshot over here
Didn’t ClarionMag have an article on this subject too? I cannot locate anything at the moment though.
Please do report back your results @Swindy and hopefully others who have been down the path can also chime in with helpful hints!
