Confluence Cloud からのスペースのインポート

As of 16 July 2019, usernames are no longer included in space exports from Confluence Cloud.

Email matching is available in selected Confluence versions. See below for more information.

The user base of your Confluence Cloud and Confluence Server or Data Center sites are seperate. Although the same people may have accounts in both sites, the way information is stored about them is different. For example, in Confluence Cloud usernames have been replaced by email addresses, and they have an additional ID (a random string of characters) that acts as a unique identifier. 

When you import a space into Confluence we attempt to attribute content based on username. If the two usernames match, we will attribute content to the user. 

In spaces exported from Cloud, where there is no username, we will attempt to match users by their email address. To reduce the risk of making restricted pages visible to the wrong person, imported content will be attributed to 'unknown user' if:

  • the email address is used by multiple user accounts (with different usernames), or
  • the user account doesn't have an email address (for example if it is private, and not included in the export).

メール照合は、Confluence Server および Data Center の次のバージョンでのみ利用できます。

  • 6.6.14 以降の 6.6 エンタープライズ リリース バージョン
  • 6.13.5 以降の 6.13 エンタープライズ リリース バージョン
  • 6.15.4 以降

他のすべてのバージョンでは、ユーザー名で照合できない場合、コンテンツは "不明なユーザー" に関連付けられます。

Confluence Cloud からのスペースのインポート

To import a small space from Confluence Cloud:

  1. In Confluence Cloud, export the space to XML
  2. In Confluence Server, go to  > General ConfigurationBackup & Restore
  3. 下にスクロールして [Confluence データを復元] に移動し、エクスポート ファイルを選択します。 
  4. インポートを選択します。   

To import a large space, the steps are the same, however we recommend dropping the export file into your home directory, rather than uploading it via your browser. See Restoring a Space for more details. 


About unknown users

スペース エクスポートで見つかったすべての Cloud ユーザー アカウントで、既存の Server / Data Center ユーザーとに照合されないものは、[ディレクトリから非同期] 一覧に表示されます。これらはメール アドレスまたは ID によって一覧表示される場合があります (これは Cloud ユーザーがメール アドレスを非公開にしているかどうかによって異なります)。 

Permissions and restrictions are respected, so if a space or page is restricted to just one of these users, it will not be visible to other people. An administrator will need to restore permissions after the import is complete. 

Here's an example of how unknown users may appear in a page. 

Restore permissions and restrictions

If the content you import is not attributed to existing users, there will be some work to do to restore the correct permissions to the right people. People may not be able to see the space until you do this. 

Restore space admin permissions

First step is to make sure the space has at least one space administrator.  To do this:

  1. Go to  > General Configuration > Space Permissions.
  2. 新しくインポートされたスペースの横にある [権限の回復] を選択します。
  3. [権限の管理] を選択します。これにより、そのスペースの [権限] ページが表示されます。 
  4. ユーザーまたはグループに、そのスペースのスペース管理権限を付与し、変更内容を保存します。 

confluence-administrators スーパー グループのメンバーの場合は、ステップ 2 と 3 をスキップして、スペースに直接移動できます。 

Restore space permissions

Now that the space has at least one space admin, they can restore any other permissions. 

  1. スペースに移動して、サイドバーの下部から、スペース ツール > 権限を選択します。
  2. Grant each user the desired permissions. It can be useful to have the space permissions screen in Confluence Cloud open while you do this. 

As long as any groups are named the same in Cloud and Server / Data Center you shouldn't need to make any changes to groups. If your groups aren't named the same, you can add any relevant groups at this point. 

Restore page restrictions

Pages with view restrictions applied in Confluence Cloud may be associated with unknown users in Server / Data Center. This means the pages won't be visible.

Space admins can remove individual page restrictions 

  1. スペースに移動して、サイドバーの下部から、スペース ツール > 権限を選択します。
  2. [制限されたページ] タブに移動します。閲覧または編集の制限があるページが一覧表示されます。 
  3. ページの横にある鍵アイコンをクリックして、閲覧制限を削除します。 
  4. If the page is still restricted, use your browser back button and click the padlock beside another View restriction. Repeat this process until enough restrictions have been removed that you can see the page (you'll land on Page Information). 
  5. > [制限] を選択します。  
  6. You can now reinstate the view and edit restrictions. It can be useful to have the Cloud page open to refer to. 

Removing restrictions so that you can see the page may mean that the page becomes temporarily visible to others. If this is a concern you can either apply a temporary view restriction to a parent page, or perhaps remove space permissions until you've finished restoring the right view restrictions. 

Understanding the risks

When importing a space from Confluence Cloud, there's a small risk that content is attributed to the wrong user, which would make any restricted pages visible to the wrong person. This is because the only information we can use to match the user is their email address, which can be changed by the user themselves or by an administrator.

It's essential that email addresses are associated with the correct user accounts. Content may be attributed to the wrong user account if the email address has been changed maliciously, or accidentally, for example if a username and email combination has been reused, so that a former and current employee share the same username and email address. 

We mitigate this risk by only associating content to user accounts that have a unique email address. We don't match accounts with no email address, or where the same email address has been used for multiple user accounts with different usernames, even if they exist in different user directories. 

However, if the space you are importing is sensitive, you may want to manually check whether there have been any changes to email addresses recently, before importing a space from Confluence Cloud.
