You need to activate CodeTwo Office 365 Migration after the trial license has expired. Follow the links below to learn how to:


CodeTwo Office 365 Migration requires internet access to connect to our licensing service and perform the activation.

Activating the program for the first time

To activate the program, open CodeTwo Office 365 Migration. On the Dashboard, you will find the Help card containing the Licensing link. Click that link to open the Licensing window (Fig. 1.).

If you’re activating the program after the demo version has expired, the License key field will display the trial key that’s no longer valid. To enter the license key you received after purchasing the software, click the Activate button and paste the key in the Program activation window (Fig. 2.). Click Activate to complete the process and close that window.

Be careful when starting the migration process right after the activation. The migration job that you set up in the trial version will still be present on the Jobs tab in the Administration Panel. If you click Run delta migration, the previously migrated source mailboxes will be counted by the licensing program and will take licenses from the available pool.

Before starting or restarting the migration, make sure that the configured pairs of mailboxes / public folders are the ones that you want to migrate. If not, remove them by selecting a particular mailbox and choosing Unmatch target mailbox.

Activating the program after an upgrade

If you’re activating the program after upgrading it from version 2.x to 3.x, the License key field (see Fig. 2.) will contain your product license key. Follow the same steps as described above to complete the activation. However, be sure to read this article before clicking the Activate button. 

Updating the number of available licenses after expanding the license

If you purchased licenses for additional mailboxes, you don't need to reactivate the program. The license count will be refreshed automatically within an hour or so.

However, you can speed up the process by performing the same steps as described above. The License key field (see Fig. 2.) will already contain your product license key, so simply click the Activate button to connect to our licensing system and update the number of mailboxes that you can migrate.
