Upgrading CubeIDE1.9 to 1.12

[LMorr.3]

I created many projects using CubeIDE1.9. I now installed CubeIDE1.12 and need to open my projects in the new version. I copied my old projects to a new workspace I created and then tried to import/open projects using CubeIDE1.12 but got a generic 'error' with no details when I try to open some of them.

How do I upgrade my projects from CubeIDE1.9 to CubeIDE1.12?

More details please? Windows or Linux? Which STM32?

Can you share an example project from CubeIDE 1.9?

The issue was resolved. It was related to the .cproject file having been duplicated from another project without renaming the contents. CubeIDE1.12 would quit with an unknown error.

I also had to use import 'Existing Projects into Workspace' instead of 'Projects from Folder or Archive'

Yes, this is not quite intuitive. When you want to import projects as is, without any conversion - use "Existing Projects into Workspace".

But I rarely, if ever, had to edit .cproject files for renaming a project.

Usually change of the name in .project file is enough.
