# Assume we are in your home directory cd ~/ # Clone the repo from GitLab using the `--mirror` option $ git clone --mirror [email protected]:mario/my-repo.git # Change into newly created repo directory $ cd ~/my-repo.git # Push to GitHub using the `--mirror` option. The `--no-verify` option skips any hooks. $ git push --no-verify --mirror [email protected]:mario/my-repo.git # Set push URL to the mirror location $ git remote set-url --push origin [email protected]:mario/my-repo.git # To periodically update the repo on GitHub with what you have in GitLab git fetch -p origin git push --no-verify --mirror
when migration has big file issue:
1). Clone with –mirror from Gitlab git clone --mirror https://your-gitlab-site.com/mario/my-repo.git 2). Use BFG to clear tree and reduce repo size java -jar bfg-1.13.0.jar --strip-blobs-bigger-than 50M my-repo.git git reflog expire --expire=now --all && git gc --prune=now –-aggressive 3). Push to github with --mirror git push --mirror --no-verify https://github.com/mario/my-repo.git > push.log 2>&1
这样会有一个问题，这种情况bfg会保护当前版本(HEAD所指的版本)，不去清理。提示如下:
Protected commits ----------------- These are your protected commits, and so their contents will NOT be altered: * commit ******* (protected by 'HEAD')
解决方法：
java -jar bfg-1.13.0.jar --strip-blobs-bigger-than 50M my-repo.git --no-blob-protection
