How to change domain for a project of other companies emails

[Liucija Bakanaitė]

We have a situation where a customer organization (project) changed their email domain from @company1 to @company2, while keeping the same email usernames. We'd like to know whether it's possible to bulk update these users in our Jira Service Management project or if they have to change their Atlassian account emails individually.

Can you please provide detailed instruction on how to do it?

Hi Liucija,

Regarding your concern about bulk updating email addresses, the Atlassian administration UI does not have built-in functionality for executing bulk email address changes.

There are REST API endpoints available to Org Admin to execute the changes in bulk. These are mentioned in a corresponding public feature request in which we're tracking interest in bulk domain change functionality:

• ID-7821: Ability to Bulk Change Email Domain on Users

I strongly recommend you vote on this feature request and drop a comment for further updates. Please, note that all of the feature requests are implemented following our Feature Request Policy.

The Organizations API is available to list all the managed accounts in your Organization. You can use this to enumerate the unique Atlassian account ID for each user.

The User management API is available to edit individual users. Use Update a user profile endpoint to update the email address.
