Hi feifanji,
There a few topics on the community related to such migration. Which toolbox and which S32DS are you using.
E.g. for S32K144 Toolbox we have an automatic way for importing project via ProjectInfo.xml Importer
And everything is ready for building and debugging.
For the other toolboxes and other versions of S32DS we do not have yet such support therefore you need to add the files manually one by one starting from a Hello World project created within the S32DS.
Hope this helps!
Daniel
