Success of Installation on Transition Exchange 2003 and 2007

Hi back to my previous topic on transitioning Exchange 2003 to Exchange 2007.

I have my snapshot of the successful installation.

If you noticed during the installation, the Routing group between Exchange 2003 and Exchange server 2007 is created. Please see image below. This should be unchanged. The routing group is installed by default.

After that, you can view the mailbox of user in exchange server 2007. When you view their mailbox, in Exchange 2007, it will view Legacy Mailbox. This means that the mailbox is still stored in Exchange 2003 environment. Please see image below:

Another process example of mailbox user has been moved to Exchange 2007 mailbox database. please see image below:


To move mailbox, Expand Recipient Organization and choose Mailbox, right click the name of user mailbox and choose Move Mailbox. what you only have to do is to choose the mailbox store of Exchange 2007

After success moving mailbox, I also attach another image to show the sample of the different type of recipient mailbox store on image below.

Transition Exchange 2003 to Exchange 2007

Can you upgrade Exchange 2003 to Exchange 2007?

the answer is “no”.

so How? do I need to uninstall it?

you may don’t want to to do that if you have exchange server 2003 in the organization. You still can have your exchange 2003 alive in your company. What you need to do is to add new server that runs Exchange 2007, but yet it’s costly because your production server which is Exchange server 2007 needs 64 bit processor. There is no 32 bit for exchange server 2007 unless for trial version.

There are many pre-requisites to make your hand dirty.

On your domain controller, you need to raise up domain functional level to windows server 2003 and your exchange server should be in Native Mode.

To checkĀ  domain functional level. -> go to Active Directory for Users and Computers -> right click the servername -> Domain Functional level – If still Windows server 2000 native mode, change it to window server 2003

To check Exchange Server Organization. -> go to your exchange server -> Open Exchange System Manager. Right-click the server and properties

Extract your exchange server 2007 installer to the drive. In my case, I use Exchange server 2007 SP 1 32 bit trial version.


This is needed to run so that it will check the exchange server compatibility.
