Top 5 Answer for Rename a git submodule

Git1.8.5 (October 2013) should simplify the process. Simply do a:

git mv A B 

"git mv A B", when moving a submodule A has been taught to relocate its working tree and to adjust the paths in the .gitmodules file.


See more in commit 0656781fadca1:

Currently using "git mv" on a submodule moves the submodule's work tree in that of the superproject. But the submodule's path setting in .gitmodules is left untouched, which is now inconsistent with the work tree and makes git commands that rely on the proper path -> name mapping (like status and diff) behave strangely.

Let "git mv" help here by not only moving the submodule's work tree but also updating the "submodule.<submodule name>.path" setting from the .gitmodules file and stage both.
This doesn't happen when no .gitmodules file is found and only issues a warning when it doesn't have a section for this submodule. This is because the user might just use plain gitlinks without the .gitmodules file or has already updated the path setting by hand before issuing the "git mv" command (in which case the warning reminds him that mv would have done that for him).
Only when .gitmodules is found and contains merge conflicts the mv command will fail and tell the user to resolve the conflict before trying again.


git 2.9 (June 2016) will improve git mv for submodule:

mv: allow moving nested submodules

"git mv old new" did not adjust the path for a submodule that lives as a subdirectory inside old/ directory correctly.

submodules however need to update their link to the git directory as well as updates to the .gitmodules file.

I found following workflow working:

  • Update .gitmodules
  • mv oldpath newpath
  • git rm oldpath
  • git add newpath
  • git submodule sync

Note: this approach does not update the index and .gitmodules properly in 2018 versions of GIT.

Note: You may be able to now just do git mv oldpath newpath now, as pointed out in VonC's answer. (Ensure you are using the latest version of git)

The correct solution is:

mv oldpath ~/another-location git rm oldpath git submodule add submodule-repository-URL newpath

I just tried a few of the suggested above. I'm running:

$ git --version git version 1.8.4 

I found it was best to de-init the submodule, remove the directory and create a new submodule.

git submodule deinit <submodule name>  git rm <submodule folder name>  git submodule add <address to remote git repo> <new folder name> 

At least that is what worked for me best. YMMV!

It's not possible to rename it, so you've to remove it first (deinit) and add it again.

So after removing it:

git submodule deinit <path> git rm --cached <path> 

you may also double check and remove the references to it in:

  • .gitmodules
  • .git/config
  • remove reference folder from .git/modules/<name> (best to make a backup), as each folder has config file where it keeps the reference to its worktree

then stage your changes by committing any changes to your repo by:

git commit -am 'Removing submodule.' 

and double check if you don't have any outstanding issues by:

git submodule update git submodule sync git submodule status 

so now you can add the git submodule again:

git submodule add --name <custom_name> git@github.com:foo/bar.git <my/path>
