iPhone: Changing XCode project name is safe?

Question

I could change XCode project name with the answer: https://stackoverflow.com/a/4954029/709950 .

Project file (.xcodeproj) and target name were changed.
But source folder name and scheme name doesn't changed.

I found the way to change scheme name by myself.
And I found the way to change source folder name on: https://stackoverflow.com/a/8344066/709950

Is it safe to change project name in the above way?
Are there anything I have to do to change project name completely?
Or is it safer and more clean to create new project and copy source files to it?

EDIT:
I found that committing of GIT of XCode doesn't work anymore after renaming project name.

And found a question about this problem:
How do I rename an xcode scheme and keep Git commit working?

But the solution which is answered in that question is too complex for me to accept.

EDIT2:
I tried to re-create git repository after the above problem happened.
But I couldn't re-create. So I asked how to do it.
And I got a good answer.

Answer 1

If you wanna change the application name, you just change the project name. All the rest is insignificant ( relax about the folder name and scheme ).
