Git migrator for Bitbucket
We support migrating these entities from Bitbucket:
- Repository
- Repository Public/Private status
- Pull requests
- Pull request comments
- Webhooks
- Branch Rules
Items that would not imported or imported differently:
- Pull request reviewers and approvers
- Pending tasks/comments
- Any attachment
- LFS objects
- Webhooks: Some webhook events are not supported. You can check supported triggers here
Estimating export duration
Export will depend on the size of repo and its pull request. A repo which has more pull request but less comments will take more time than one which has more comments and lesser pull requests.
Prerequisites
To export workspaces from Bitbucket, you must have admin write access in for the workspace to successfully export all the supported entities.
Users
All the users encountered anywhere are stored by email and can be found in users.json in the exported zip file. You need to use a workplace access token to list user email addresses. Emails of past workspace members are not accessible due to Bitbucket's compliance with GDPR.
Installing
You can install the migrator via github releases or run make build with latest go version present in your system.
Branch Protection and Webhooks
When they are exported, supported Bitbucket branch protection rules and webhooks are stored in zip file, which later during import to harness code are mapped according to:
Webhooks
| Bitbucket events | Harness Code events |
|---|---|
| Repository Push | Branch Created, Branch Updated, Branch Deleted, Tag Created, Tag updated, Tag Deleted, PR branch updated |
| Repository Commit comment created, Pull request Comment created | PR comment created |
| Pull request Created | PR created |
| Pull request Updated | PR updated, PR branch updated |
| Pull request Merged | PR merged |
Branch protection rules
| Bitbucket rule(set) | Harness Code rule |
|---|---|
| Restrict creations | Block branch creation |
| Restrict deletions | Block branch deletion |
| Restrict updates | Block branch update |
| Require linear history | Require pull request |
| Require a pull request before merging | Require pull request |
| Dismiss stale pull request approvals when new commits are pushed | Require approval of new changes |
| Require approval of the most recent reviewable push | Require approval of new changes |
| Require review from Code Owners | Require review from code owners |
| Require conversation resolution before merging | Require comment resolution |
| Block force pushes | Block force push |
Commands
As a quick start you can run
./migrator bitbucket git-export --workspace <workspace name> --repository <repo-name> --host <host-url> --username <bitbucket-username> --token <token> <zip-folder-path>
where you have to replace all values enclosed in brackets <>.
You can also provide more advanced options. You can look at those via help:
./migrator bitbucket git-export --help
Application also supports advanced option like resume which can help you resume run from last successful run and avoid overhead of re-running the same commands.
Troubleshooting
General
Missing tasks or comments on the pull requests
Please make sure to Finish Review on open pull requests before starting the export. Pending comments and task will not be exported.
Export fails due to reach the Bitbucket rate limit
If project export fails due to reaching the Bitbucket API rate limit, you could wait for an hour and re-run the migrator or exclude exporting metadata (options available are --no-pr, --no-comment, --no-webhook, and --no-rule)
Export fails due to missing permission
If you see errors in listing webhooks, make sure the provided token has admin permission.
Missing webhooks or branch rules
If you see missing items for any webhooks or branch rules you can refer ExporterLogs.log file in root of zip folder.
Webhooks don't have all the events
As of now all webhook events are not supported and you can check ExporterLogs.log file to get error logs.
