Question

Is there any way to move submodules within your superproject without removing them first and re-adding them ?

Answer 1

It’s similar to how you removing a submodule (see How do I remove a submodule?):

• Edit .gitmodules and change the path of the submodule appropriately, and put it in the index with git add .gitmodules
• If needed, create the parent directory of the new location of the submodule: mkdir -p new/parent
• Move all content from the old to the new directory: mv -vi old/parent/submodule new/parent/submodule
• Remove the old directory with git rm --cached old/parent/submodule

Looks like this for me afterwards:

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       modified:   .gitmodules
#       renamed:    old/parent/submodule -> new/parent/submodule
#

• Finally commit the changes.
