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