No email downtime occurs during migration.

It doesn't affect DNS or the ability to send or receive emails: it simply performs an IMAP sync to move emails from one server to another.

The Migration Process

  • Uses IMAP synchronisation technology to transfer messages between servers
  • Does not interrupt DNS functionality
  • Maintains continuous sending and receiving capabilities
  • Causes zero service interruption
