Review email domains before the migration

All of your users should have an email address from some domain, for example @atlassian.com. To keep your cloud site secure, you can migrate only users from trusted domains.

Before you migrate, you’ll need to:

• Use the migration assistant to view the email domains that we found in your user directory

• Review the domains and mark them as trusted. This is required to migrate.

• Remove untrusted domains by deleting users or changing their emails to other domains

Review all email domains

You can review your email domains directly in the migration assistant or by using a CSV file. Here’s a sample Review all domains screen from the migration assistant:

1. Bulk actions: If the number of domains is high, you can use the CSV file to update them in bulk. *This is not available in Bitbucket Cloud.

2. Search and filter: You can search for specific domains, change ordering by selecting the column names, or filter by decision status. This can help you find the domains that you need to review.

3. Domains: The list includes all domains found in your user directory, together with some details, such as the number of users from each domain, decision chosen, or action required for a specific domain.

Your goal is to mark all email domains as trusted. If there are domains you don’t trust, you need to get them removed from the list. Just marking them as not trusted won’t let you migrate.

Review email domains using the migration assistant

You can review your email domains in the Jira and Confluence migration assistants.

To review your email domains:

1. Open the Jira or Confluence migration assistant.

2. Access the Review all email domains screen:

   1. If it’s your first migration, select the Review all email domains card on the home screen.

   2. If it’s a subsequent migration, create or run a migration from the Migrations dashboard. A message will appear asking you to review email domains, where you can select Review all email domains.

3. When prompted, connect to your cloud site. This step is needed so we can display accurate information about users.

4. Select Begin assessing to find and assess domains from your user directory.

5. After the assessment is complete, review each email domain and mark it with one of the following decisions:

Once you've marked all your domains as trusted, select Done to complete the domain review. If there are domains you can’t trust, read further below for information on how to remove them from the list.

Review email domains using a CSV file

You can also review your email domains in bulk by using a CSV file. This is useful if you have a high number of domains. Any changes you’ve made directly in the assistant will be reflected in the file. Likewise, you can make more changes after uploading the file back. *This is not available in Bitbucket Cloud.

To use the CSV file:

1. Access the Review all email domains screen. For detailed steps, see the section above.

2. Select Download CSV file.

3. Edit the file and mark each domain with a decision. Here are some details about the file:

   • The CSV file includes all email domains found in your user directory.

   • You can change the decision for each domain, but you can’t add or delete domains.

   • The values are: NO_DECISION_MADE, NOT_TRUSTED, or TRUSTED.

4. When you’re ready, upload the CSV file back. The decisions from the file will be reflected in the assistant.

Once all your domain are marked as trusted, select Done to complete the domain review. If there are domains you can’t trust, read further below for information on how to remove them from the list.

Workaround: Trusting and clearing all domains at once

If you really need to select all domains as trusted or clear all your selections, you can use these URLs in your browser bar. Again, check the warning above.

How you can remove untrusted domains

Unless you trust all email domains, you won’t be able to migrate.

When you don’t trust an email domain, you need to review users from such a domain in your Server or Data Center instance, and either delete them or change their email addresses to other domains. Once that’s done, the domains won’t appear on the list.

Use one of the following methods to modify user details to be able to unblock the migration:

• User administration tools in Jira and Confluence Server or Data Center

• Modify users from external directories

Use admin tools to modify users

Use the existing user administration tools in your Server or Data Center products to review all the users with untrusted domains. To do so, search for the untrusted domain and modify, disable, or delete the user.

1. Select Administration > User management.

2. On the next Users screen, search for the domain you don’t trust.

3. From the list that appears, select the user to be modified.

4. Edit the user details such as the email ID or username.

Modify users in your external directories

Take one of the following approaches to modify the users in your external directories:

• Modify the emails of the users with untrusted domains to addresses of domains you trust

• Delete the users with emails containing untrusted domains

Modify the emails of the users with untrusted domains to addresses of domains you trust

Delete the users with emails containing untrusted domains

How to review email domains if you have already migrated to cloud

If you’ve already migrated emails from untrusted domains to cloud, you can either:

• Suspend users. This keeps their identity, but blocks the access.

• Delete users. All references to deleted users will appear as Former user.
