Licensing

The licensing model of CodeTwo Exchange Migration is based on the total number of source mailboxes that will be migrated. Each migrated mailbox consumes one license. Regardless of the number of licenses that you purchased, you will only receive one license key. The key contains information on how many mailboxes can be migrated with the software. You can run several migration jobs on multiple machines using the same license key until you run out of individual licenses.

A single license is consumed for each source mailbox matched in the Match Mailboxes step when you start a migration job. Once the job starts, reassigning a license to another source mailbox is no longer possible. Mailboxes are counted by the licensing system only once, based on their GUID. Mailbox GUID is also the only piece of information about your user that is stored in our licensing system. We do not store SMTP email addresses or any other Active Directory data associated with a mailbox.

Source mailboxes that have already been counted by the licensing system can be migrated as many times as you want. There is no risk that the same source mailbox will use more than one license when you restart the migration, use the rescan button, configure a new job with the same mailboxes, etc.

Note that when matching mailboxes, the software lists all source mailboxes in the alphabetical order. If you decide to buy a license key for fewer mailboxes than the number of mailboxes existing in your organization, you will have to manually choose mailboxes that you want to migrate. If you need to migrate more mailboxes, you can buy additional licenses at any time.

Example:

You bought a license key that allows you to migrate 50 source mailboxes. You have already migrated 25 mailboxes to another server. As a result, you still have 25 licenses left. You can use them to migrate mailboxes from any other Exchange Server or IMAP source – migration via IMAP takes the same number of licenses as the migration of Exchange mailboxes.

Accessing licensing details

To see detailed information on your license, including the number of mailboxes that you can migrate, go to Dashboard and in the Help card click the Licensing link. This will open the Licensing window (Fig. 1.).

Important

The program's licensing service requires an internet connection to retrieve information regarding your license.

The Licensing window displays:

  • your license key;
  • the type of your license (full or trial);
  • the date when your license will expire / has expired. In the case of CodeTwo Exchange Migration, the license is unlimited in time;
  • the Buy/Expand button that links to the order from where you can purchase the license key or buy additional individual licenses;
  • the number of available and already consumed licenses.

The Licensing window also contains the Activate button. Read this article to find out more about activating the program.

Public Folders Migration

Note that the migration of public folders takes 25 licenses out of the license pool. This number is fixed and doesn't depend on the actual number of the migrated public folders or their size. 

Example:

You bought a license key for 50 source mailboxes and then migrated the source public folders to the target server. You will still be able to migrate 25 mailboxes or public folders from any other Exchange Server or IMAP source.

Using the same license key on multiple machines

Once a license is consumed to migrate a specific source mailbox, attempting to migrate the same mailbox by using another instance of the program (installed on a different PC) will not consume another license. Keep in mind, however, that only the information about the license being used is shared between these machines, not the information about the migrated data itself.

Warning

For that reason, we don't recommend migrating data between the same source and target servers on two or more different machines, as it could end up creating duplicated items on the target mailboxes.
