Question: How do you migrate projects in PSoC® Creator™ 1.0 to Creator 2.0 or later versions?
Delete the “Generated Source” directory and all of its contents from the Workspace Explorer from Creator. In case some files in the Generated Source hierarchy have user-modified code, then choose No in the Yes/No/Cancel dialog that appears upon clicking Delete so that user code will be preserved the next time you run code generation. Rebuild the project(s). The project will now build successfully.
