Microsoft Exchange Server 2013 Setup displayed this warning because no Exchange Server 2010 or Exchange Server 2007 server roles exist in the organization.
 Caution: |
|---|
| If you continue with Exchange Server 2013 installation, you won’t be able to add Exchange 2010 or Exchange 2007 servers to the organization at a future date. |
Before deploying Exchange 2013, consider the following factors that may require you to deploy Exchange 2010 or Exchange 2007 servers prior to deploying Exchange 2013:
- Third-party or in-house developed
applications Applications developed for
earlier versions of Exchange may not be compatible with Exchange
2013. You may need to maintain Exchange 2010 or Exchange 2007
servers to support these applications.
- Coexistence or migration
requirements If you plan on migrating
mailboxes into your organization, some solutions may require the
use of Exchange 2010 or Exchange 2007 servers.
If you decide that you need to deploy Exchange 2010 or Exchange 2007 servers, you must do so before you deploy Exchange 2013. Active Directory must be prepared for each Exchange version in the following order:
- Exchange 2007
- Exchange 2010
- Exchange 2013
