Before you activate CodeTwo Exchange Migration, you must first install the Trial version of the program.

To activate the program, you need to use the License Key received after finalizing your order.


The license key can only be used on one particular machine. Furthermore, once the program is activated the key cannot be reused on another machine.

To start the Licensing program, open CodeTwo Exchange Migration. On the Dashboard you will find Help tile containing Licensing link - simply click on it. Please activate the program in the window that opens by entering the license key and clicking Activate over the Internet (Fig. 1.).

After activating the program, the number of available licenses will display in the License Status field of the Licensing program (Fig. 2.).

From now on you will be able to use CodeTwo Exchange Migration without any limits. However, as the program works for a particular number of source mailboxes, please remember that it will not work for any extra source mailboxes exceeding the original number of licenses.


After activating your program, the already set migration in the trial version will still be present in Administration Panel, so please be extremely careful while starting the migration process after activation. If you instantly hit Rescan the previously migrated source mailboxes will be counted in the licensing program straightaway and take away licenses from the available pool. That is why before starting or restarting migration make sure that the configured pairs of mailboxes / public folders are the ones that you want to migrate. If not, you can always remove them by selecting a particular mailbox and choosing Unmatch target mailbox.

To activate any of the CodeTwo programs, you need to be connected to the Internet. However, if you encounter any Internet access issues you may also activate your program via e-mail. Click Activate manually and follow 3 steps described in the Manual activation window that opens (Fig. 3.).
