how to migrate from git hub to git hub

i want to move all the git hub content on a server to git hub on another server. I want to know what are the limitations and best method to migrate. I have tried using git clone/push but this is not complete solution there are few links like pull requests, issues, milestones, labels which are not migrated. Guide me with API to be used to migrate all and how to test post migration

Hi @ksvshankar,

Thanks for being here! Hopefully one of our user here can share their own experience with migrations. In the meanwhile perhaps the API docs on moving projects to or from GitHub could be helpful.
