Email Migration is a process in which an email or multiple email messages are migrated from one email client to another email client.[1] An equivalent term is Mailbox Migration, in which case records such as e-mails, appointments, contacts or tasks may also be migrated. In general, email migration is required when a user is switching from its current email client to a new one. Usually, email clients don't support similar file formats for saving mailbox data.[citation needed]
Scenarios
Mailboxes may be migrated for different reasons.[2] For example, mailboxes may need to be migrated because a company wants to use a new email service provider. Or mailboxes may need to be migrated following a company acquisition or merger. In most cases, a simple one-time migration approach may be employed. However, more advanced scenarios exist, including:
- Consolidation: email migration is performed to consolidate multiple accounts into one, for example following an employee's departure.
- Backup: email migration is performed to back up or preserve data, for example, to ensure legal compliance.
- Coexistence: email migration is performed for evaluation purposes, for example during a migration pilot.
- Upgrade: email migration is performed to facilitate an upgrade, for example when deploying a new version of an email system.
Procedure
Various technical procedures are normally used to achieve email migration:
- Email forwarding: this allows a mailbox to forward received content to a designated email address.
- MX record modification: this allows a mail server to process emails on behalf of a designated SMTP domain.
- Content conversion: this allows content to be converted, for example from TNEF to MIME format.
- Property mapping: this allows properties to be mapped, for example from Gmail to Exchange contacts.
- Copy Email: Make a copy of an email from a source mailbox to a destination mailbox
Features
Email migration solutions may implement different features which determine their suitability for different migration scenarios:
- Supported systems: defines the list of source and destination systems supported (ex: IMAP, Gmail, Exchange).
- Administrative logins: allows administrative login to multiple user mailboxes (ex: using OAuth).
- Multi-pass migrations: allows multiple migrations pass without creating duplicates.
- Scalability: allows a large set of mailboxes to be migrated concurrently.
- Monitoring: allows administrators to monitor migration progress and receive alerts.
- Analytics: allows administrators to access statistics such as transfer speed, error rate, etc.
- Reliability: allows the migration process to automatically handle or retry errors during migration.
- Filtering: allows migration of specific content (ex: date range) from specific locations (ex: folders).
- Security: allows migrated content to remain secure, for example using SSL encryption.
