- Introduced in GitLab 8.9.
- From GitLab 10.0, administrators can disable the project export option on the GitLab instance.
Existing projects running on any GitLab instance or GitLab.com can be exported with all their related data and be moved into a new GitLab instance.
The GitLab import/export button is displayed if the project import option is enabled.

- Group import/export API
To set up a project import/export:
- On the top bar, go to Menu > Admin > Settings > General > Visibility and access controls.
- Scroll to Import sources.
- Enable the desired Import sources.
Note the following:
- Before you can import a project, you must export the data first. See Export a project and its data for how you can export a project through the UI.
- Imports from a newer version of GitLab are not supported. The Importing GitLab version must be greater than or equal to the Exporting GitLab version.
- Imports fail unless the import and export GitLab instances are compatible as described in the Version history.
- Exports are generated in your configured
shared_path, a temporary shared directory, and are moved to your configured
uploads_directory. Every 24 hours, a specific worker deletes these export files.
- Group members are exported as project members, as long as the user has a maintainer or administrator role in the group where the exported project lives.
- Project members with the Owner role are imported as Maintainers.
- Imported users can be mapped by their public email on self-managed instances, if an administrative user (not an owner) does the import.
Additionally, the user must be an existing member of the namespace, or the user can be added as a
member of the project for contributions to be mapped.
Otherwise, a supplementary comment is left to mention that the original author and
the MRs, notes, or issues are owned by the importer.
- For project migration imports performed over GitLab.com Groups, preserving author information is possible through a professional services engagement.
- If an imported project contains merge requests originating from forks, then new branches associated with such merge requests are created in a project during the import/export. Thus, the number of branches in the exported project could be bigger than in the original project.
- Deploy keys allowed to push to protected branches are not exported. Therefore, you must recreate this association by first enabling these deploy keys in your imported project and then updating your protected branches accordingly.
In GitLab 14.0, the JSON format is no longer supported for project and group exports. To allow for a transitional period, you can still import any JSON exports. The new format for imports and exports is NDJSON.
Starting with GitLab 13.0, GitLab can import bundles that were exported from a different GitLab deployment. This ability is limited to two previous GitLab minor releases, which is similar to our process for Security Releases.
|Current version||Can import bundles exported from|
|13.0||13.0, 12.10, 12.9|
|13.1||13.1, 13.0, 12.10|
Prior to 13.0 this was a defined compatibility table:
|Exporting GitLab version||Importing GitLab version|
|11.7 to 12.10||11.7 to 12.10|
|11.1 to 11.6||11.1 to 11.6|
|10.8 to 11.0||10.8 to 11.0|
|10.4 to 10.7||10.4 to 10.7|
|10.0 to 10.2||10.0 to 10.2|
|9.4 to 9.6||9.4 to 9.6|
|9.2 to 9.3||9.2 to 9.3|
|8.17 to 9.1||8.17 to 9.1|
|8.13 to 8.16||8.13 to 8.16|
|8.10.3 to 8.11||8.10.3 to 8.11|
|8.10.0 to 8.10.2||8.10.0 to 8.10.2|
|8.9.5 to 8.9.11||8.9.5 to 8.9.11|
|8.9.0 to 8.9.4||8.9.0 to 8.9.4|
Projects can be exported and imported only between versions of GitLab with matching Import/Export versions.
For example, 8.10.3 and 8.11 have the same Import/Export version (0.1.3) and the exports between them are compatible.
If you’re exporting a project from the Enterprise Edition to the Community Edition, you may lose data that is retained only in the Enterprise Edition. For more information, see downgrading from EE to CE.
The following items are exported:
- Project and wiki repositories
- Project uploads
- Project configuration, excluding integrations
- Issues with comments, merge requests with diffs and comments, labels, milestones, snippets, time tracking, and other project entities
- Design Management files and data
- LFS objects
- Issue boards
- Pipelines history
- Push Rules
The following items are not exported:
- Build traces and artifacts
- Container registry images
- CI/CD variables
- Pipeline triggers
- Any encrypted tokens
- Merge Request Approvers
- Repository size limits
Full project export functionality is limited to project maintainers and owners. You can configure such functionality through project settings:
To export a project and its data, follow these steps:
Go to your project’s homepage.
Click Settings in the sidebar.
Scroll down to find the Export project button:
After the export is generated, you should receive an email with a link to download the file:
Alternatively, you can come back to the project settings and download the file from there, or generate a new export. After the file is available, the page should show the Download export button:
The GitLab project import feature is the first import option when creating a new project. Click on GitLab export:
Enter your project name and URL. Then select the file you exported previously:
Click on Import project to begin importing. Your newly imported project page appears shortly.
You can query an import through the Project import/export API. As described in the API documentation, the query may return an import error or exceptions.
If you have a larger project, consider using a Rake task, as described in our developer documentation.
To help avoid abuse, by default, users are rate limited to:
|Export||6 projects per minute|
|Download export||1 download per group per minute|
|Import||6 projects per minute|
GitLab.com may have different settings from the defaults.
- Ensure shared runners are enabled in both the source and destination projects.
- Disable shared runners on the parent group when you import the project.
Maximum import size limitations can prevent an import from being successful. If changing the import limits is not possible, the following local workflow can be used to temporarily reduce the repository size for another import attempt.
Create a temporary working directory from the export:
EXPORT=<filename-without-extension> mkdir "$EXPORT" tar -xf "$EXPORT".tar.gz --directory="$EXPORT"/ cd "$EXPORT"/ git clone project.bundle # Prevent interference with recreating an importable file later mv project.bundle ../"$EXPORT"-original.bundle mv ../"$EXPORT".tar.gz ../"$EXPORT"-original.tar.gz git switch --create smaller-tmp-main
# Reduce the .git/objects/pack/ file size cd project git reflog expire --expire=now --all git gc --prune=now --aggressive # Prepare recreating an importable file git bundle create ../project.bundle <default-branch-name> cd .. mv project/ ../"$EXPORT"-project cd .. # Recreate an importable file tar -czf "$EXPORT"-smaller.tar.gz --directory="$EXPORT"/ .
- Import this new, smaller file into GitLab.
- In a full clone of the original repository,
git remote set-url origin <new-url> && git push --force --allto complete the import.
- Update the imported repository’s
branch protection rules and
its default branch, and
delete the temporary,
smaller-tmp-mainbranch, and the local, temporary data.
Exports sometimes fail without giving enough information to troubleshoot. In these cases, it can be helpful to execute the export process manually within rails. Execute each line individually, rather than pasting the entire block at once, so you can see any errors each command returns.
