Exchange Server 2019 has brought a new set of features and changes in its environment to make it safer and adaptable with minimum resources. Its main goal is to help businesses that want to shift their focus from communication to collaboration. The overall price of on-premises Exchange Server 2019 is also reduced substantially compared to other current versions. Instead of using complex network rules and firewalls, the internal administration can be completed through the Client Access Rule.

The search features created for Exchange Online are now part of Exchange 2019, which helps the indexing of larger files, easier management, and faster search performance. Outlook Web App has a new name with ‘Outlook on the Web’ where the Exchange is available on all web browsers.

Migrate mailboxes from 2013 to 2019

After installing Exchange 2019, you have two servers in your environment, and your next requirement is to migrate from the older 2013 to the new 2019. You can complete the process in Exchange Admin Center by migrating the mailboxes-

  1. Log in to Exchange Admin Center and go to recipients, then mailboxes. Select the mailboxes that you need to migrate to the new server.
  2. Click the Add (+) option and select ‘move to a different database.’
  3. Choose more mailboxes for migration in the next window and click Next.
  4. Provide a new name to the batch migration and choose the database in which you want to migrate. Choose the database from Exchange Server 2019. You can opt if you want to migrate the primary mailbox, public folder, or archive mailbox. Click Next.
  5. Add a user who will receive notifications of migration stages. Click Next.
  6. Choose either to start the batch instantly or after a scheduled time. It gives you control to run the batch at a later time when the Exchange Server has a lesser load.
  7. The final step of creating the migration batch is to either automatically complete the migration batch or manually complete it by clicking the ‘complete this migration batch’ link.
  8. As soon as a new batch is created, it will appear in the migration category. You can start it when you feel comfortable with the migration.

There will be a small delay in synchronization between the mailboxes as Active Directory replication may connect with their mailboxes depending on the location of the Exchange Server. After Active Directory syncs with the account completely, then you can further move mailbox in Exchange 2019 from 2013 again.


The manual migration from Exchange Server 2013 to 2019 may take much time to move large mailboxes and databases. As there can be different Exchange Migration methods, you can also choose professional software to migrate mailboxes. Kernel Migrator for Exchange can migrate mailboxes between any version of Exchange Server, and the number of features is also greater than any manual method. You can apply several filters and schedule the migration at any appropriate time.

There is a pre-migration analysis that will inform you about the possible outcomes of the migration procedure. It also provides a complete migration report after successful completion.
