Reminder to all repository users: Please do not add , commit and push any data files to your remote git repositories. The disk space the Git server is limited, it wasn't dimensioned to host anything else than code. Solely your code files need versioning. The data inputs/outputs don't. A good idea is to do "git add" individually on each file you want to commit, to avoid versioning unwanted content.

In addition to the specific migration documentation above, you can import any Git repository via HTTP from the New Project page. Be aware that if the repository is too large the import can timeout.

You can copy your repos by changing the remote and pushing to the new server; but issues and merge requests can't be imported.
