Automatic migration

Auto-migration enables you to migrate users and their emails without resetting passwords, importing them into the system manually, or performing email data migration for each user.

How it works

Set up auto migration for a domain with your existing (source) IMAP server details
Your users can then sign up from the login page
The system checks their credentials with the source IMAP server, creates an account for them and migrates the emails
