Plan your Cloud migration
Documents to help you prepare to migrate your Atlassian Server or Data Center products.
This page shows options available in the migration assistant to automatically fix invalid email addresses.
Start with the user assessment
If you stumbled here by accident, make sure to start with the landing page that shows how to run the assessment and update important users in your user directory.
Check this information before you start.
If you have an external directory, we recommend that you update important users manually, and then apply the Migrate invalid users as Former users option to the remaining users. Treating users with invalid emails as former users and migrating them as such helps you avoid problems after you sync the directory to cloud.
Choose one of the automatic options to fix the remaining users during migration.
The changes will be applied to users created in Cloud, not your original users.
The changes won’t be applied right away, but only after you start a migration.
We won’t make any changes. Your migration will be blocked unless you update users in your user directory.
Users will be migrated as Former user in Cloud. A former user:
Is deactivated, can’t log in, and can’t be restored
Doesn’t consume a license
Has every activity, such as comments or history, preserved but displayed under the name ‘Former user’
It’s a container that groups activity from all former users, for example deleted users
In Server or Data Center | In Cloud |
---|---|
| Users don’t exist as separate entities, you can’t view them. Any activity is displayed as Former user. |
Users who last logged in before the chosen date or who never logged in:
Are migrated as Former user in Cloud. For more info, see the Migrate invalid users as Former users above.
Users who logged in after the chosen date:
Receive pre-generated email addresses and are migrated as active users. For more info, see the Create new emails option below.
Users get pre-generated email addresses that unblock the migration, because they’re valid. Users with such emails:
Are migrated as active users
Consume the license if they’re migrated into a group with product access
Have every activity, such as comments or history, preserved and correctly displayed under their name
Can’t log in, because they don’t have access to the email address
This option isn’t used to preserve access for users, but to preserve their identity. The email address is based on userID and a domain most common in your user directory.

Use the CSV file to apply to fixes to your users in a more granular way, for example by migrating most of them as Former users and only selecting just a few that should get new email addresses.
If the assessment also identified duplicated email addresses, see Fix duplicated email addresses in simple experience. If not, select Review changes where you can apply the changes to your migrations.
