It is surprising that most of the search results related to moving Git repository is targeted towards moving repositories to github.com and alike. I was trying to move my git repository from, say, server1.edu to server2.edu. These servers are Linux servers and are accessible via SSH. However, using the common set of instructions i.e. git clone --bare followed by git push --mirror kept throwing me following error:
And it turns out that the answer is very simple and is actually explained on Git documentation. Just perform a local --bare clone of the repository then scp or rsync it to server and update origin of the repository. Thats it! All push/pull would work as expected after that with new server. Here are steps I followed (notice server1 and server2 in the commands):
$ git push -v --mirror ssh://server2.edu:/home/user/Repo.git
Pushing to ssh://server2.edu:/home/user/Repo.git
fatal: '/home/user/Repo.git' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Some posts suggested to first initialize a git repository on server. This sounded odd to me as per my understanding, all we need is SSH access to the server in order to setup as a remote Git repository.And it turns out that the answer is very simple and is actually explained on Git documentation.
