Email archive migration software
Moving historic email between archive platforms can be a complex undertaking, particularly when organisations need to preserve access to business-critical information, maintain compliance and minimise disruption to users.
Ultimate Migrator provides specialist email archive migration software to help organisations migrate, consolidate and modernise their email archives. Our technology supports migrations from platforms including Enterprise Vault, Mimecast, Barracuda, Proofpoint and legacy Exchange environments into Microsoft 365, Microsoft Exchange and other supported destinations.
Whether you’re replacing a legacy archive, consolidating email systems or migrating PST files, Ultimate Migrator helps address common challenges:
- Large volumes of historic email distributed across multiple systems and locations.
- Complex migration requirements involving different source and destination platforms.
- Corrupt, inaccessible or problematic messages that require exception handling.
- The need to preserve important email information and maintain appropriate access.
- Limited visibility of migration progress, failures and outstanding exceptions.
- Pressure to reduce infrastructure costs and decommission legacy archive platforms.
Our software combines automated discovery, migration management, configurable processing, error handling and detailed reporting. A web-based management console provides visibility and control throughout the migration project, helping organisations manage large-scale email archive migrations efficiently.
PST migration: a three-stage process
PST files can present significant challenges for organisations managing historic email. They may be scattered across servers, laptops and workstations, making them difficult to discover, protect and manage centrally. PST migration allows organisations to consolidate this information into a supported email or archive platform.
Ultimate Migrator provides an automated approach to PST discovery, ownership assignment and migration, reducing manual effort while providing visibility and control throughout the process.
1) Discover and locate PST files
Discovering PST files is the first stage of a successful PST migration project. In larger organisations, thousands of PST files may be distributed across file servers, workstations, laptops and remote offices. Identifying and cataloguing these files manually can be time-consuming, resource-intensive and prone to error.
Ultimate Migrator automates PST discovery across distributed environments, identifying files wherever they are stored. Our software also verifies that discovered files contain valid Outlook PST data, helping organisations build an accurate inventory before migration begins.
This provides a reliable foundation for migration planning, allowing teams to understand the scale of their PST estate and identify files requiring further investigation.
2) Identify and assign PST file owners
Correctly identifying the owner of each PST file is essential to ensuring that historic email is migrated to the appropriate destination.
Ultimate Migrator uses automated ownership identification techniques that consider multiple factors during the discovery process. Configurable rules help organisations associate PST files with the correct users, reducing the risk of incorrect assignments and unnecessary manual investigation.
Where ownership cannot be established confidently, files can be identified for further review before migration. This helps organisations maintain control over where historic information is transferred and reduces the risk of messages being assigned to the wrong mailbox or archive.
3) Schedule and automate PST migration
Once PST files have been discovered and their owners identified, Ultimate Migrator can automate the migration of their contents into supported destinations, including Microsoft 365, Microsoft Exchange and Enterprise Vault.
Migration processing can be scheduled and managed centrally, with multithreaded processing supporting larger migration projects.
Our software is designed to manage common migration challenges, including:
- Corrupt or inaccessible messages within PST files.
- Temporary network or destination connectivity problems.
- Mailbox and archive storage limitations.
- Interrupted migration jobs requiring retries.
- Exceptions requiring investigation or manual intervention.
Configurable retry handling, exception reporting and progress monitoring help migration teams identify issues without unnecessarily interrupting the wider migration project.
The Ultimate Migrator web-based management console provides centralised visibility of migration activity, helping administrators monitor progress, investigate exceptions and manage migration projects across distributed environments.
