How do I replace a git submodule with another repo?

Question

How do I replace a git submodule with a different git repo?

Specifically, I have a submodule:

• located at ./ExternalFrameworks/TestFramework

Answer 1

If you want to change the remote URL only for this clone:

git config submodule."$submodule_name".url "$new_url"

This won't affect the .gitmodules file in the parent project, so it won't be propagated to other developers.

This is described as "user specific record changes" here.

Do not run git submodule sync as that will reset to the default URL again.
