Exporting migration data from .com

1. Ensure that you have owner permissions on the source organization's repositories.

2. Generate an access token with the repo and admin:org scopes on .com.

3. To minimize downtime, make a list of repositories you want to export from the source instance. You can add multiple repositories to an export at once using a text file that lists the URL of each repository on a separate line.

To export repository data from .com, use the Migrations API.

The Migrations API is currently in a preview period, which means that the endpoints and parameters may change in the future.

1. Notify members of your organization that you'll be performing a migration. The export can take several minutes, depending on the number of repositories being exported. The full migration including import may take several hours so we recommend doing a trial run in order to determine how long the full process will take. For more information, see About ghe-migrator.

2. Start a migration by sending a POST request to the migration endpoint. You'll need:

   • Your access token for authentication.

   • A list of the repositories you want to migrate:

     curl -H "Authorization: Bearer _ACCESS_TOKEN" \
     -X POST \
     -H "Accept: application/vnd.+json" \
     -d'{"lock_repositories":true,"repositories":["ORG_NAME/REPO_NAME", "ORG_NAME/REPO_NAME"]}' \
     https://api..com/orgs/ORG_NAME/migrations
     

   • If you want to lock the repositories before migrating them, make sure lock_repositories is set to true. This is highly recommended.

   • You can exclude file attachments by passing exclude_attachments: true to the endpoint. File attachments can be large and may needlessly bloat your final migration archive. The final archive size must be less than 20 GB.

   This request returns a unique id which represents your migration. You'll need it for subsequent calls to the Migrations API.

3. Send a GET request to the migration status endpoint to fetch the status of a migration. You'll need:

   • Your access token for authentication.

   • The unique id of the migration:

     curl -H "Authorization: Bearer _ACCESS_TOKEN" \
     -H "Accept: application/vnd.+json" \
     https://api..com/orgs/ORG_NAME/migrations/ID
     

   A migration can be in one of the following states:

   • pending, which means the migration hasn't started yet.
   • exporting, which means the migration is in progress.
   • exported, which means the migration finished successfully.
   • failed, which means the migration failed.

4. After your migration has exported, download the migration archive by sending a GET request to the migration download endpoint. You'll need:

   • Your access token for authentication.

   • The unique id of the migration:

     curl -H "Authorization: Bearer _ACCESS_TOKEN" \
     -H "Accept: application/vnd.+json" \
     -L -o migration_archive.tar.gz \
     https://api..com/orgs/ORG_NAME/migrations/ID/archive
     

5. The migration archive is automatically deleted after seven days. If you would prefer to delete it sooner, you can send a DELETE request to the migration archive delete endpoint. You'll need:

   • Your access token for authentication.

   • The unique id of the migration:

     curl -H "Authorization: Bearer _ACCESS_TOKEN" \
     -X DELETE \
     -H "Accept: application/vnd.+json" \
     https://api..com/orgs/ORG_NAME/migrations/ID/archive
     

6. To prepare the archived migration data for import into a Enterprise Server instance, see Migrating data to Enterprise Server.
