Migrating Repositories from ADO to GitHub: Need Help with PRs

That's a great question! I think a major reason is all the cool plugins available for GitHub, like Copilot. Some claim ADO has support for similar tools, but many find those versions to be buggy and not as well-tested.

One approach is to write code to recreate the PRs and their comments since there's no straightforward migration path for that. Personally, I think it's best to close all open PRs, migrate the main branch, and start fresh. If you face pushback from the team about any long-lived branches, that's a good indicator that a reset could be beneficial and you might want to shift towards trunk-based development.

By the way, what’s the main reason for migrating? ADO isn’t going away anytime soon.

PRs and comments don't transfer neatly during migration, so keep that in mind.

Another option is to back up your ADO environment and restore it in GitHub. Tools like GitProtect allow you to use their backup & DR solution to do this effectively. While it's primarily for data protection, it does facilitate data migration with a cross-restore option from ADO to GitHub.
