Easily migrate from any version of Microsoft Exchange Server to Microsoft 365. 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!

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 invaluable during company mergers or acquisitions.

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.

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.

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.

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.

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.

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.

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.

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.
