So, my exchange organization is in mixed mode, it must be changed to native mode.  In general, there is three prerequisites that must checked before installing exchange 2007, they are:

• Active Directory forest:
  • the domain functionality level must be windows 2000 or Windows Server 2003
  • the domain controller that is the schema master is running Windows Server 2003 SP1 or higher
  • the Global Catalog server is running Windows Server 2003 SP1 or higher

There are some switches that you can run them to prepare the environment by preparing the permission required for exchange 2007, preparing the schema, preparing active directory, and preparing domain.  Those switches are:

Setup.com /PrepareLegacyExchangePermissions
Setup.com /PrepareSchema
Setup.com /PrepareAD
Setup.com /PrepareDomain or Setup.com /PrepareAllDomains

Note: you can run the 32-bit version of Exchange 2007 from the trial CD to prepare you environment.

• Exchange organization
  • it is a must to run the exchange organization in native mode
  • because of this all Exchange servers running Exchange 5.5 or earlier must be removed

In my case I have to change the organization mode simply by opening the exchange system manager, right click exchange organization, choose properties then choose the change mode button you will get a warning message, click yes, as simple as that.
