See an overview of the paths available for migration to GitHub from other products, or between GitHub products.
About migration paths to GitHub
If you're moving between GitHub products, such as from GitHub Enterprise Server to GitHub Enterprise Cloud, or from another code hosting platform, such as Bitbucket Server or GitLab, to GitHub, you'll want to bring your work with you: your code, the code's history, and all of your past conversations and collaboration.
To plan for your migration, consider the destination and source. These considerations determine the path for your migration. For some migration paths, we offer specialist tools that allow you to migrate source, history, and metadata. For others, you'll need to perform a simpler "source and history" or "source snapshot" migration.
Some migration paths require tools that are only available with expert-led migrations. For more information, contact your account manager on GitHub's Sales team or see the GitHub Expert Services website.
In our recommendations, we'll assume that you want the highest level of fidelity if possible, which includes source, history, and metadata.
