이 버전의 GitHub Enterprise Server는 2023-09-25. 중요한 보안 문제에 대해서도 패치 릴리스가 이루어지지 않습니다. 성능 향상, 향상된 보안, 새로운 기능을 위해 최신 버전의 GitHub Enterprise로 업그레이드합니다. 업그레이드에 대한 도움말은 GitHub Enterprise 지원에 문의하세요.

GitHub Enterprise Server에서 마이그레이션 데이터 내보내기

플랫폼을 변경하거나 평가판 인스턴스에서 프로덕션 인스턴스로 이동하려면 인스턴스를 준비하고, 리포지토리를 잠그고, 마이그레이션 보관 파일을 생성하여 GitHub Enterprise Server 인스턴스에서 마이그레이션 데이터를 내보낼 수 있습니다.

Preparing the GitHub Enterprise Server source instance

  1. Verify that you are a site administrator on the GitHub Enterprise Server source. The best way to do this is to verify that you can SSH into the instance.

  2. Generate an access token with the repo and admin:org scopes on the GitHub Enterprise Server source instance.

  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.

Exporting the GitHub Enterprise Server source repositories

Note: Locking a repository prevents all write access to the repository. You cannot associate new teams or collaborators with a locked repository.

If you're performing a trial run, you do not need to lock the repository. When you migrate data from a repository that's in use, GitHub strongly recommends locking the repository. For more information, see "About ghe-migrator."

  1. SSH into your GitHub Enterprise Server instance. If your instance comprises multiple nodes, for example if high availability or geo-replication are configured, SSH into the primary node. If you use a cluster, you can SSH into any node. For more information about SSH access, see "Accessing the administrative shell (SSH)."

    ssh -p 122 admin@HOSTNAME
  2. To prepare a repository for export, use the ghe-migrator add command with the repository's URL:

    • If you're locking the repository, append the command with --lock. If you're performing a trial run, --lock is not needed.

      ghe-migrator add https://HOSTNAME/USERNAME/REPO-NAME --lock
    • You can exclude file attachments by appending --exclude_attachments to the command. File attachments can be large and may needlessly bloat your final migration archive.

    • To prepare multiple repositories at once for export, create a text file listing each repository URL on a separate line, and run the ghe-migrator add command with the -i flag and the path to your text file.

      ghe-migrator add -i PATH/TO/YOUR/REPOSITORY_URL.txt
  3. When prompted, enter your GitHub Enterprise Server username:

    Enter username authorized for migration:  admin
  4. When prompted for a personal access token, enter the access token you created in "Preparing the GitHub Enterprise Server source instance":

    Enter personal access token:  **************
  5. When ghe-migrator add has finished it will print the unique "Migration GUID" that it generated to identify this export as well as a list of the resources that were added to the export. You will use the Migration GUID that it generated in subsequent ghe-migrator add and ghe-migrator export steps to tell ghe-migrator to continue operating on the same export.

    > 101 models added to export
    > Number of records in this migration:
    > users                        |  5
    > organizations                |  1
    > repositories                 |  1
    > teams                        |  3
    > protected_branches           |  1
    > pull_request_reviews         |  1
    > milestones                   |  1
    > issues                       |  3
    > pull_requests                |  5
    > pull_request_review_comments |  4
    > commit_comments              |  2
    > issue_comments               | 10
    > issue_events                 | 63
    > releases                     |  3
    > attachments                  |  4
    > projects                     |  2

    Each time you add a new repository with an existing Migration GUID it will update the existing export. If you run ghe-migrator add again without a Migration GUID it will start a new export and generate a new Migration GUID. Do not re-use the Migration GUID generated during an export when you start preparing your migration for import.

  6. To add more repositories to the same export, use the ghe-migrator add command with the -g flag. You'll pass in the new repository URL and the Migration GUID from Step 5:

    ghe-migrator add https://HOSTNAME/USERNAME/OTHER-REPO-NAME -g MIGRATION-GUID --lock
  7. When you've finished adding repositories, generate the migration archive using the ghe-migrator export command with the -g flag and the Migration GUID from Step 5:

    $ ghe-migrator export -g MIGRATION-GUID
    > Archive saved to: /data/github/current/tmp/MIGRATION-GUID.tar.gz
    • To specify where migration files should be staged append the command with --staging-path=/full/staging/path. Defaults to /data/user/tmp.
  8. Close the connection to your GitHub Enterprise Server instance:

    $ exit
    > logout
    > Connection to HOSTNAME closed.
  9. Copy the migration archive to your computer using the scp command. The archive file will be named with the Migration GUID:

    scp -P 122 admin@HOSTNAME:/data/github/current/tmp/MIGRATION-GUID.tar.gz ~/Desktop
  10. To prepare the archived migration data for import into a GitHub Enterprise Server instance, see "Preparing to migrate data to GitHub Enterprise Server".
