Summary

Learn what to do when your user migration fails with "Reached limit of email aliases for a single user during".

Overview

User accounts are created in Atlassian's Cloud based on their email address during the user migration.

For security reasons, Atlassian rate-limit the creation of users with canonical emails, like the below example:

john.doe+business@gmail.com
john.doe+personal@gmail.com

As the email address is the primary user identifier in the cloud (also for billing purposes), it's recommended that each user has a unique and valid email address.

Solution

Use the migration assistant's built-in tool to identify and fix invalid email addresses before the migration:

• Invalid email addresses in the migration user assessment check
