Solved: Migrate Bitbucket Repositories to GitHub (Including Branches/Tags)

🚀 Executive Summary TL;DR: Managing projects across both Bitbucket and GitHub creates workflow inefficiencies and context-switching for engineering teams. This guide provides a script-based solution to migrate Bitbucket repositories to GitHub, ensuring all branches, tags, and commit history are fully preserved. 🎯 Key Takeaways The migration process leverages two core Git commands: git clone –bare to copy the entire repository database locally, and git push –mirror to push all references (branches, tags) to the new GitHub remote. Essential prerequisites include admin access on both Bitbucket and GitHub, a GitHub Personal Access Token (PAT) with repo scopes, a Bitbucket App Password with repository:admin permissions, and local installations of Git and Python 3. Destination repositories on GitHub must be created as completely empty, without any initial files like READMEs or licenses, for the git push –mirror command to function correctly. A Python script automates the repetitive task of c
