Auto-migration (recommended)
Automatic migration feature is available from Mail Portal > Auto 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 (top-right corner)
-
The system checks their credentials with the source IMAP server, creates an account for them and migrates the emails
Caveats
- Migration is performed concurrently for up to a maximum of 2 users only so as not to put undue load on source server.
-
Migration speed depends heavily on source server performance (latency & bandwidth) and total number (& size) of emails for each user being migrated, so it is not possible to estimate migration time easily. Having considered that, on average you could expect to transfer up to 1 GB of emails every hour per user being migrated.
-
Migration for each user would timeout after 24 hours, this is to prevent large mailboxes from holding back migration for other users waiting in queue.
-
If a migration times out, or there were un-recoverable errors during migration, or there were too many errors during migration, the migration is stopped for that user with an error status. Migration for users in error status can be resumed by resyncing migration for that user which would put them back in queue, whereupon migration is continued from where it was last interrupted, i.e., already migrated mails will not be migrated again.
-
If a user’s migration is in error status for two or more times, please contact us.
