During transitions from Bitbucket to GitLab, teams may still push code to Bitbucket. Keeping both Bitbucket and GitLab repositories in sync ensures nothing gets lost, avoids disruption, and allows for a gradual migration.
There are two reliable ways to synchronize repositories: Option 1 is using GitLab's built-in repository mirroring, and Option 2 is syncing using GitLab CI/CD and Bitbucket webhooks.
Option 1: Using GitLab Repository Mirroring: Set up mirroring in GitLab project settings, provide Bitbucket repository URL, and choose the sync interval.
Option 2: Sync Using GitLab CI/CD and Bitbucket Webhooks: Add a .gitlab-ci.yml file to both Bitbucket and GitLab repositories, configure GitLab CI/CD variables, create a pipeline trigger token in GitLab, and add a webhook in Bitbucket.
