git submodule upgrade

• Delete the relevant section from the .gitmodules file. The section would look similar to:

[submodule "3rd/mongoose"]
	path = 3rd/mongoose
	url = https://github.com/cesanta/mongoose.git

Command is:

git config -f .gitmodules --remove-section submodule.3rd/mongoose

• Stage the .gitmodules changes via command line using:

	git add .gitmodules	

• Delete the relevant section from .git/config, which will look like:

[submodule "3rd/mongoose"]
	url = https://github.com/cesanta/mongoose.git

git config -f .git/config --remove-section submodule.3rd/mongoose

• Run:

	git rm --cached 3rd/mongoose	

• Delete the now untracked submodule files:

	rd /S /Q 3rd\mongoose	
	git submodule add --force https://github.com/cesanta/mongoose.git 3rd/mongoose

• Revert changes for the .gitmodules file:

	git checkout -- .gitmodules	

• Update the submodule to specific tag:

	cd 3rd\mongoose
	git reset --hard 6.5 

• Finally just commit the changes:

git commit -m "fix(mongoose): upgrade to v 6.5"
git push -u origin master
