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
