Email archive migration

Fast, no stress migration

Get a fixed-price service that moves your email records quickly, securely & seamlessly.

Essential has performed hundreds of enterprise email archive migrations and some of the largest, most complex carried out to date.

We know what it takes to achieve the fastest results along with zero downtime for your end users and full auditing for your legal department.

Ever mindful of the fact that budgets are always stretched, we can also empower your own IT team to take a DIY approach to completing a migration.

Above all, we work closely with all the relevant stakeholders to ensure a migration that meets IT, end user and business and legal needs.

“The migration approach certainly worked for us so we do not hesitate in recommending this approach to other organisations. We had no issues and no surprises and achieved our objective to migrate all archived email from EAS to the Exchange 2010 Online archive mailboxes. Essential delivered what was promised at the outset.”

Modernise your archives

On-prem archives lead to excessive cost, inconvenience & risk:

  • Maintenance is expensive:  Annual support & licencing costs & ongoing server, storage & backup overheads quickly mount up.
  • Access is awkward:  Accessing archives may require a VPN connection or a separate interface to Outlook. Archive shortcuts (aka stubs) in Exchange Online can work across the network, but this is unsupported & can create problems ‘down the track’.
  • Compliance is complex:  You’ll need to govern data retention & carry out eDiscovery in multiple places at once.

By migrating legacy archives into the cloud you can reduce your storage costs, give end users secure, anytime, anywhere access to their data and manage the retention and security of your organisation’s data all in one place.

Super Fast

High-speed connectors are available to connect into most source and target archive systems, delivering optimum speed without negative impact on your network or live email/archive services.

User Aware

Archives often work by leaving shortcuts in users’ mailboxes. As we migrate your archives we will check their current location and status, and either convert or remove them as needed.

This means no surprises ‘post migration’ that could have a negative impact on user productivity and the ‘end user experience’.


Our archive migration technology is proven in over 2,500 migrations and is trusted by major vendors including Veritas and Microsoft.
