Moving git repository and all its branches, tags to a new remote repository keeping commits history

git.migrate

#!/bin/bash
# Sometimes you need to move your existing git repository
# to a new remote repository (/new remote origin).
# Here are a simple and quick steps that does exactly this.
#
# Let's assume we call "old repo" the repository you wish
# to move, and "new repo" the one you wish to move to.
#
### Step 1. Make sure you have a local copy of all "old repo"
### branches and tags.
# Fetch all of the remote branches and tags:
git fetch origin

# View all "old repo" local and remote branches:
git branch -a

# If some of the remotes/ branches doesn't have a local copy,
# checkout to create a local copy of the missing ones:
git checkout -b <branch> origin/<branch>

# Now we have to have all remote branches locally.


### Step 2. Add a "new repo" as a new remote origin:
git remote add new-origin [email protected]:user/repo.git


### Step 3. Push all local branches and tags to a "new repo".
# Push all local branches (note we're pushing to new-origin):
git push --all new-origin

# Push all tags:
git push --tags new-origin


### Step 4. Remove "old repo" origin and its dependencies.
# View existing remotes (you'll see 2 remotes for both fetch and push)
git remote -v

# Remove "old repo" remote:
git remote rm origin

# Rename "new repo" remote into just 'origin':
git remote rename new-origin origin


### Done! Now your local git repo is connected to "new repo" remote
### which has all the branches, tags and commits history.

Than you so much

@niksumeiko Hi! I need to migrate from GH Enterprise to GH Enterprise Cloud. Is there a possibility to migrate all the closed Pull Requests as well? I can't find any GH REST API that helps(for obvious reasons I guess). Do you guys feel that if the code is merged and the base branches are already deleted why do we need to migrate those closed PR#s?

@astiw2, there's totally a way to do GH Enterprise migration (incl. all pull requests, issues…), but not via the git command line. Please consult with GH enterprise support people. They serve us wonderful. We're also on their Enterprise tyre.

Personally I think that it's much better to do it this way:

git clone --mirror URL
git remote add NEW-REMOTE URL
git push  NEW-REMOTE --mirror 

@prashathsenthil You have to run these commands as below

git clone --mirror <url_of_old_repo>
cd <name_of_old_repo>
git remote add new-origin <url_of_new_repo>
git push new-origin --mirror

Thanks very much, I do it in this way , migrate all the branches in the repository from gerrit to gitlab successfuuly.

can this work for Gitlab? I have a branch on a Company Gitlab project and I would like to see my contributions on my GitHub?

Is there a method to pull from git and migrate elsewhere such as svn for instance on a local repo with history? I've searched these internet pages a few months now and not much has come up.

git clone --bare {repo}
cd {project}.git
git push --mirror {new-repo}

This is the way.

Please no one do this. And unlike above comment, should use mirror the whole time.

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