How to migrate GIT repository from one server to a new one

Solution 1:

To add the new repo location,

git remote add new_repo_name new_repo_url

Then push the content to the new location

git push new_repo_name master

Finally remove the old one

git remote rm origin

After that you can do what bdonlan said and edit the.git/config file to change the new_repo_name to origin. If you don't remove the origin (original remote repository), you can simply just push changes to the new repo with

git push new_repo_name master

Solution 2:

If you want to migrate all branches and tags you should use the following commands:

git clone --mirror [oldUrl]

to clone the old repo with all branches

cd the_repo
git remote add remoteName newRepoUrl

to setup a new remote

git push -f --tags remoteName refs/heads/*:refs/heads/*

to push all refs under refs/heads (which is probably what you want)

Solution 3:

Updated to use git push --mirror origin instead of git push -f origin as suggested in the comments.

This worked for me flawlessly.

git clone --mirror <URL to my OLD repo location>
cd <New directory where your OLD repo was cloned>
git remote set-url origin <URL to my NEW repo location>
git push --mirror origin

I have to mention though that this creates a mirror of your current repo and then pushes that to the new location. Therefore, this can take some time for large repos or slow connections.
