Migrating data to GitHub Enterprise Server

Applying the imported data on GitHub Enterprise Server

Before you can migrate data to your GitHub Enterprise Server, you must prepare the data and resolve any conflicts. For more information, see "GitHub Enterprise Server へのデータ移行の準備."

After you prepare the data and resolve conflicts, you can apply the imported data on GitHub Enterprise Server.

サイト管理者として、ターゲットの GitHub Enterprise Server インスタンスに SSH で接続します。
```
$ ssh -p 122 admin@HOSTNAME
```
Using the ghe-migrator import command, start the import process. You'll need:
- Your Migration GUID. For more information, see "GitHub Enterprise Server へのデータ移行の準備."
- Your personal access token for authentication. The personal access token that you use is only for authentication as a site administrator, and does not require any specific scope. For more information, see "個人用アクセストークンの作成."
```
$ ghe-migrator import /home/admin/MIGRATION-GUID.tar.gz -g MIGRATION-GUID -u USERNAME -p TOKEN

> Starting GitHub::Migrator
> Import 100% complete /
```
- 移行ファイルをステージングする場所を指定するには、--staging-path=/full/staging/path を使用してコマンドを追加します。既定値は /data/user/tmp です。

Reviewing migration data

By default, ghe-migrator audit returns every record. It also allows you to filter records by:

The types of records.
The state of the records.

The record types match those found in the migrated data.

Record type filters

Record type	Filter name
Users	`user`
Organizations	`organization`
Repositories	`repository`
Teams	`team`
Milestones	`milestone`
Project boards	`project`
Issues	`issue`
Issue comments	`issue_comment`
Pull requests	`pull_request`
Pull request reviews	`pull_request_review`
Commit comments	`commit_comment`
Pull request review comments	`pull_request_review_comment`
Releases	`release`
Actions taken on pull requests or issues	`issue_event`
Protected branches	`protected_branch`

Record state filters

Record state	Description
`export`	The record will be exported.
`import`	The record will be imported.
`map`	The record will be mapped.
`rename`	The record will be renamed.
`merge`	The record will be merged.
`exported`	The record was successfully exported.
`imported`	The record was successfully imported.
`mapped`	The record was successfully mapped.
`renamed`	The record was successfully renamed.
`merged`	The record was successfully merged.
`failed_export`	The record failed to export.
`failed_import`	The record failed to be imported.
`failed_map`	The record failed to be mapped.
`failed_rename`	The record failed to be renamed.
`failed_merge`	The record failed to be merged.

Filtering audited records

With the ghe-migrator audit command, you can filter based on the record type using the -m flag. Similarly, you can filter on the import state using the -s flag. The command looks like this:

$ ghe-migrator audit -m RECORD_TYPE -s STATE -g MIGRATION-GUID

For example, to view every successfully imported organization and team, you would enter:

$ ghe-migrator audit -m organization,team -s mapped,renamed -g MIGRATION-GUID
> model_name,source_url,target_url,state
> organization,https://gh.source/octo-org/,https://ghe.target/octo-org/,renamed

We strongly recommend auditing every import that failed. To do that, you will enter:

$ ghe-migrator audit -s failed_import,failed_map,failed_rename,failed_merge -g MIGRATION-GUID
> model_name,source_url,target_url,state
> user,https://gh.source/octocat,https://gh.target/octocat,failed
> repository,https://gh.source/octo-org/octo-project,https://ghe.target/octo-org/octo-project,failed

If you have any concerns about failed imports, contact GitHub Enterprise サポート.

Completing the import on GitHub Enterprise Server

After your migration is applied to your target instance and you have reviewed the migration, you''ll unlock the repositories and delete them off the source. Before deleting your source data we recommend waiting around two weeks to ensure that everything is functioning as expected.

Unlocking repositories on the target instance

お使いの GitHub Enterprise Server インスタンスに SSH で接続します。インスタンスが複数のノードで構成されている場合は (高可用性や geo レプリケーションが構成されている場合など)、プライマリノードに SSH 接続します。クラスターを使用する場合は、任意のノードに SSH 接続できます。 SSH アクセスについて詳しくは、「管理シェル (SSH) にアクセスする」をご覧ください。
```
$ ssh -p 122 admin@HOSTNAME
```
ghe-migrator unlock コマンドを使用して、インポートされたすべてのリポジトリのロックを解除します。移行GUIDが必要になります。
```
$ ghe-migrator unlock -g MIGRATION-GUID
> Unlocked octo-org/octo-project
```

Unlocking repositories on the source

Unlocking repositories from an organization on GitHub.com

To unlock the repositories on a GitHub.com organization, you'll send a DELETE request to the migration unlock endpoint. You'll need:

Your access token for authentication
The unique id of the migration
The name of the repository to unlock

curl -H "Authorization: Bearer GITHUB_ACCESS_TOKEN" -X DELETE \
  -H "Accept: application/vnd.github.wyandotte-preview+json" \
  https://api.github.com/orgs/ORG-NAME/migrations/ID/repos/REPO_NAME/lock

Deleting repositories from an organization on GitHub.com

After unlocking the GitHub.com organization's repositories, you should delete every repository you previously migrated using the repository delete endpoint. You'll need your access token for authentication:

curl -H "Authorization: Bearer GITHUB_ACCESS_TOKEN" -X DELETE \
  https://api.github.com/repos/ORG-NAME/REPO_NAME

Unlocking repositories from a GitHub Enterprise Server instance
