Transitioning from exchange 2000 to 2007 (Part 2)

It is recommended to run the latest version of Exchange best practice analyzer tools now, and choose Exchange 2007 readiness check, in my case, the tool gave me the following report:

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, also you must make sure that the domain controller that is the schema master is running windows server 2003 SP1 or higher, this is also applied for the Global catalog server running on the site as well.

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: /PrepareLegacyExchangePermissions /PrepareSchema /PrepareAD /PrepareDomain or /PrepareAllDomains

Note: you can run the 32-bit version of exchange 2007 to prepare you environment.

®Exchange organization: it is a must to run the exchange organization in native mode, so we have to remove any exchange servers running exchange 5.5 .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.

®Server requirements:
Software needed:

- .Net framework 2.0 and the update KB926776 as well
-MMC 3.0
-Windows PowerShell 1.0
-HotFix for Windows x64 (KB904639)

Also, there are some additional components that you have to install on the server depending on the role you are planning to implement, those are:
For Mailbox server role, you need the following components:
• Enable network COM+ access
• Internet Information Services
•World Wide Web Service

For Client Access Server, you need the following components:
-RPC over HTTP proxy
-ASP.NET 2.0

For Hub transport server role, no more components are needed.
But be sure that the SMTP AND NNTP is not installed.

For Edge transport server role, you will need ADAM
AND also make sure that SMTP AND NNTP.

In the next article we gonna start the setup........
