You are the messaging engineer for your company.
The network contains two Microsoft Exchange Server 2003 servers named Server1 and Server2. Server1 is a back-end server. Server2 is a front-end server.
You purchase a new server named Server3 that has the same hardware as Server1 and Server2.
All server hardware supports both the 32-bit and 64-bit versions of Microsoft Windows Server 2003.
You need to recommend a strategy to transition from Exchange Server 2003 to Exchange Server 2007.
Your strategy must meet the following requirements:
Minimize downtime.
Configure the solution to be supported by Microsoft for production environments.
Configure one server to provide Exchange Web Services and message delivery and a different server to manage Mailbox databases.
What should you recommend?
A.
On Server3, install the 32-bit edition of Windows Server 2003. Install the 32-bit edition of the Exchange
Server 2007 Client Access server role, Hub Transport server role, and Mailbox server role. Change the MX
records and Web services URL to point to Server3. Move all mailboxes to Server3.
B.
On Server3, install Windows Server 2003 x64 Edition. Install the 64-bit edition of the Exchange Server
2007 Client Access server role, Hub Transport server role, and Mailbox server role. Change the MX records and
Web services URL to point to Server3. Move all mailboxes to Server3.
C.
On Server2, remove the current operating system and install Windows Server 2003 x64 Edition. Install the
64-bit edition of the Exchange Server 2007 Hub Transport server role and Client Access server role. On
Server1, export all mailboxes to .pst files. On Server1, import the mailboxes to the server from the .pst files.
D.
On Server3, install Windows Server 2003 x64 Edition. Install the 64-bit edition of the Exchange Server
2007 Hub Transport server role and Client Access server role. Change the MX records and Web services URL
to point to Server3. On Server2, remove the current operating system and install the Windows Server 2003 x64
