Описание и применение

Перенос репозитория с GitHub на GitLab с сохранением рабочего процесса и CI/CD.

Migrating a large open‑source project from GitHub to GitLab while preserving existing workflow and community practices.

The project successfully transitioned to GitLab with minimal disruption to contributors and maintained the same workflow patterns.

1. Export GitHub repository data (issues, pull requests, labels, milestones).
2. Import data into GitLab using GitLab’s import tool.
3. Migrate CI/CD configuration from GitHub Actions to GitLab CI by translating workflow files.
4. Update webhooks and integrations to point to GitLab endpoints.
5. Verify that merge requests, issue comments, and CI jobs work as expected.
6. Communicate the migration to contributors and update documentation.

We migrated the repository from GitHub to GitLab while keeping our workflow intact.

The migration involved exporting GitHub data and importing it into GitLab using the built‑in import tool.
