Key Features


Exchange to Microsoft 365 migration

Easily migrate from any version of Microsoft Exchange Server to Microsoft 365 or Microsoft 365 Germany. The program will help you move your on-premises mailboxes directly to Microsoft 365. It doesn't matter which Exchange version you currently use. Exchange 2003, 2007, 2010, 2013, 2016 or 2019 – all of them can be used as the source of the migration!


Migrate between Microsoft 365 tenants

Thanks to the option to connect to the source server via EWS, you can freely migrate mailboxes between Microsoft 365 tenants. You can move all items both to an empty (new) Microsoft 365 tenant or to an existing organization, which can prove to be useful e.g. during company mergers or acquisitions.


Migrate email, calendars, contacts and more

By means of CodeTwo Office 365 Migration, users’ Exchange mailboxes are replicated to the Cloud together with all their original content and folder structure. The result of the migration is a 1:1 copy of the source Exchange mailbox in Microsoft 365. This applies to all sorts of folders supported in your target Microsoft 365 plan – email, contacts, calendars, tasks, etc.


Migrations from Exchange 2019 / 2016 / 2013 / 2010 / 2007 / 2003 and SBS to Microsoft 365

CodeTwo Office 365 Migration doesn't require you to upgrade your existing Exchange Server installation to be able to migrate to the cloud. Direct migrations from legacy Exchange servers and Small Business Server 2011, 2008 and 2003 are fully supported.


Migrate Exchange public folders to Microsoft 365

Also Exchange Server public folders can be moved to Microsoft 365 by means of CodeTwo Office 365 Migration. All you have to do is create an empty mailbox for the Public Folders in Microsoft 365 and our software will take care of the rest. In contrast to the native scenario, you do not need to perform complicated preparations, be familiar with scripting, or experience any downtime.


Support for cutover, staged and hybrid migration

The program lets you migrate mailboxes in any way you want. You can migrate all mailboxes in one go, transfer data in batches or migrate within hybrid environments. Just configure a migration job accordingly and let the software take care of everything, offering a higher level of customization than the native migration paths.


Post-migration rescan

The Rescan feature lets you scan already migrated pairs of mailboxes and public folders. If the program finds any new items, it migrates them to the target server without duplicating the content which has already been moved. This function ensures that no item is left behind after the server switch.


Support for all languages

The software supports all languages. It means that whatever language the source and the target server has set, CodeTwo Office 365 Migration will take care of migrating all special characters, so that all moved elements look the way they looked on the source server after the migration.


Migrate Google, Zimbra and more to Microsoft 365

Using CodeTwo Office 365 Migration, you can carry out a migration of emails from any server supporting IMAP, like IBM Notes (formerly Lotus Notes) or G Suite, to Exchange Online. What's more, the program gives you a wide range of filtering, scheduling and reporting options to help out with the task.


Automatically provision and license Microsoft 365 users

Don’t waste time juggling CSV files and PowerShell scripts. CodeTwo Office 365 Migration will take the task of licensing and creating mailboxes for users in the target Microsoft 365 tenant off your hands. Just run the program’s mailbox creation wizard, adjust the settings and click start!


Automatic mailbox matching

The Automatch option lets you join source and target mailboxes based on custom patterns. Thanks to this feature, the preparation stage of the migration takes a lot less time than using Microsoft’s native tools.


Folder types selection

You can now decide what kind of items are migrated. Simply place a check mark next to a folder name to process only this specific type of items - emails, contacts, calendars, notes, tasks or journals.


Scheduled migration

For many reasons administrators prefer to migrate users’ mailboxes over night or during weekends. The program comes with a convenient Scheduler feature that allows to schedule the exact time when the migration batches are supposed to be launched during the week. Moreover, you can decide which mailboxes are migrated first and which ones are next. You can assign a priority number to each mailbox to set up the migration order. This way you can push more important data first.


Install in the cloud

CodeTwo Office 365 Migration can be installed on a cloud-hosted virtual machine (for example on Microsoft Azure Virtual Server). Thanks to that, you do not have to install any software locally and you can instead migrate with multiple cloud instances. This gives you the flexibility required especially when handling multiple migration projects.


Full service availability - no downtime

With CodeTwo Office 365 Migration users can use their mailboxes while their data is copied to Microsoft 365. The program doesn’t affect the email service availability during the migration. Therefore, your users can enjoy access to their old mailboxes even while their mail items are being transferred to Microsoft 365.


Secure migration

Your users’ data stays always safe during the migration to Microsoft 365. CodeTwo Office 365 Migration creates an exact copy of the source mailbox in the target location. The program doesn't delete or modify anything in your mailbox configuration and anything that is synced to your Microsoft 365 plan is always fully encrypted. All security-related functionalities are set to active by default and comply with our ISO/IEC 27001 and ISO/IEC 27018-certified Information Security Management System.


Migration reports

The program offers detailed reports that can be generated for the overall migration process, or from a particular mailbox or job perspective. You can keep track of the migration directly in the application, or choose to receive these reports by email.


Easy configuration

CodeTwo Office 365 Migration doesn’t require you to execute any PowerShell commands in order to perform your migration. What’s more, the program comes with a built-in Automatch feature for matching mailboxes automatically on the source and target end. It also offers configuration wizards that will guide you through the process of connecting to the source and destination server.
