Refreshing a project

Hello there,

I recently created a copy of my project to convert it for the new editor version 4.11 (from 4.10). I also wanted to rename the project, but some files are still having the old name and if I rename all files I get an error that the dll file is from another engine version or missing → and it also doesn’t work to click on rebuild then.

Is there a way to properly rename and refresh the whole project? I think the most important problem here is the code, because I can’t build that aswell…

Thanks
