Are you tired of using a slow, unreliable, or insecure CI platform? Do you have a lot of old CI pipelines that you don't know how to rewrite? I will share a way that can help you to migrate your existing pipelines with ease.

GitHub Actions runners are one of the best CI runners available today. They offer both cloud-based and self-hosted runners, so you can choose the option that best suits your needs.

Many developers don't know, GitHub also offers a tool called gh-actions-importer that can help you to migrate your CI pipelines from any other platform to GitHub Actions. gh-actions-importer is a CLI-based tool that can plan, migrate, and test your pipelines in GitHub Actions. It supports a wide variety of CI platforms, so you can be sure that your pipelines will be migrated seamlessly.

In addition to gh-actions-importer, you can also use gh-cli to help you with your migration. The gh-cli can be used to add comments and tags to your pull requests, making it easy to track your progress. You can also use the gh-cli to self-host your CI runners, giving you more control over your CI environment.

I have personally used gh-actions-importer and the gh-cli to migrate CI pipelines at Mercari Japan. This helped us to migrate all of our repos from an old and insecure CI platform to GitHub Actions. I will be talking more about my experiences with this migration in my upcoming talk.
