Exchange 2007 32-bit to 64-bit

By nazish_sayeed ·
Hi,
This is Nazish.Just last month we had setup a new office.We configured a exchange 2007 enterprise 32 Bits mail server on 2003 enterprise edition.As microsoft made delay to deliver media we downloaded for site and installed trial version.
Later come to know that microsoft is not prodving 32 bits license and only 64 Bits is available.
Now we have to migrate from 32 Exchnage 2007 to 64 bit. How to do that?
Presently, as this is new office, we don't have bulky database.Its only 1 GB with 4 mail box storage.and some 50 clients.
We also have license of windows 2008 enterprise. Hardware is not an issue for us. I can make arragement of another server with same hardware too.

Please reply. I would be thankful to you for your kind help.

Regards,
Nazish Sayeed

Before you do anything, read up on the issues here:

You need 64bit hardware, it can not be installed on 32bit hardware and OS. Install 64bit Windows OS on 64bit hardware and install Exchange 2007 64bit edition.

Depending on the 64-bit processor you will have to install 64 based Windows Server OS and then install Exchange Server.

More info on 32-Bit vs. 64-Bit Version of Exchange 2007

Exchange 2007 RTM and SP1 are available in two platform versions: the 64-bit version is for live production environments and the 32-bit version is for non-production environments (such as labs, training facilities, demos, and evaluation environments). Only the 64-bit version can be purchased because you cannot run 32-bit Exchange 2007 servers in production.

There are exceptions with respect to production and non-production use of the 32-bit platform because Microsoft does allow minimal supported use of the 32-bit version in production environments:

* You can use the 32-bit version in production to extend your Active Directory directory service schema. For detailed steps about how to prepare Active Directory for Exchange 2007, see How to Prepare Active Directory and Domains.
* You can use the 32-bit version of the release to manufacturing (RTM) management tools in production to administer Exchange 2007 servers from Windows Server 2003 or Windows XP.
* You can use the 32-bit version of the Service Pack 1 (SP1) management tools on Windows Server 2008 or on Windows Vista. Support for Windows Server 2008 and Windows Vista is available only with Microsoft Exchange Server 2007 SP1. However, you cannot use the SP1 management tools (32-bit or 64-bit) on Windows Vista to remotely manage a clustered mailbox server in a failover cluster. This is because:
o Windows Server does not support cross-operating system management of failover clusters. Thus, Windows Vista cannot be used to manage a Windows Server 2003 failover cluster, and neither Windows Server 2003 nor Windows XP can be used to remotely manage a Windows Server 2008 failover cluster.
o Remote management of a Windows Server 2008 failover cluster requires the installation of the Failover Cluster Management tools, which currently do not exist for Windows Vista. Thus, Windows Vista cannot be used to remotely manage a Windows Server 2008 failover cluster.

For more information about managing mixed versions of clustered mailbox servers, see Upgrading Clustered Mailbox Servers to Exchange 2007 SP1.
Important:
All other uses of the 32-bit version of Exchange 2007 in production environments are unsupported.

Although the 64-bit version can be Standard Edition or Enterprise Edition, the 32-bit version is only Standard Edition. SCC and CCR are only supported in production on the Enterprise Edition of Exchange 2007. However, Microsoft has made an exception in the 32-bit version code to allow SCC and CCR to be used for non-production use on the 32-bit version, even though the 32-bit version is Standard Edition. This means that you can set up a 32-bit test lab for evaluating or testing SCC and CCR. Because it is 32-bit, you can create the non-production environments in a Microsoft Virtual Server environment for your lab or demos. For a video demonstration of CCR that uses a virtual environment, see Video series - Exchange 2007 Cluster Continuous Replication (CCR). For a video demonstration of SCR that uses a virtual environment, see Video Series: Exchange 2007 SP1 Standby Continuous Replication (SCR).
Note:
You can also install Unified Messaging (UM) with the 32-bit version in a non-production environment so that you can evaluate the UM-related features. For details about using a software-based UM test phone to test or demo UM features, see Testing Unified Messaging Server Functionality.
What Is Missing from the 32-Bit Version

In addition to the missing Exchange Management Console interface for entering a product key as described in "Evaluations and Product Keys" later in this topic, two other features are not available in the 32-bit version of Exchange 2007:

* Automatic anti-spam updates from Microsoft Update. Only a licensed 64-bit version of Exchange 2007 can get automatic anti-spam updates from Microsoft Update.
* Large numbers of storage groups and databases. You can have a maximum of five databases per server in as many as five storage groups on the 32-bit version.

Exchange Server 2007 SP1

Exchange 2007 SP1 is a full re-release of Exchange 2007 with SP1 already integrated. This is similar to the service pack slipstreaming model used by Windows Server; however, it is not slipstreaming, and you do not need to perform any slipstreaming tasks for Exchange 2007 SP1.
Note:
You can download SP1 from http://go.microsoft.com/fwlink/?LinkId=104387.

SP1 can be installed on computers running the RTM version of Exchange 2007 to perform an in-place upgrade. For new installations, you do not need to install Exchange 2007 RTM and then install SP1. Because SP1 is a completely updated set of installation files, it can be used to perform a fresh installation of Exchange 2007 SP1.

Exchange 2007 SP1 includes all update rollups previously released for Exchange 2007 up to and including Update Rollup 5. You do not need to manually uninstall any released update rollup (1-5). When you install Exchange 2007 SP1 on a system that has a released update rollup, the update rollup will be automatically uninstalled by SP1 Setup.
Exchange 2007 and Virtualization

Neither Exchange 2007 nor Exchange 2007 SP1 is supported in production in a virtual environment. However, Microsoft has several virtualization offerings that provide a good environment for training, labs, and demos, such as Windows Server 2008 Hyper-V, Microsoft Virtual Server 2005 R2, and Microsoft Virtual PC 2007. Exchange 2007 and Exchange 2007 SP1 are supported in production environments using only the 64-bit version of Exchange 2007, and currently neither Microsoft Virtual Server nor Microsoft Virtual PC supports 64-bit guest systems. Windows Server 2008 Hyper-V includes support for 64-bit guest systems; however, Exchange 2007 and Exchange 2007 SP1 are currently not supported running under Hyper-V. Within 60 days of the Hyper-V release to manufacturing (which occurred on June 26, 2008), Microsoft will release a support statement and related guidance for Exchange 2007 as a Hyper-V guest system.

Exchange 2007 and Exchange 2007 SP1 are not supported in production in a virtual environment using virtualization software that is not Microsoft software. For details about the Microsoft support policy for third-party virtualization software, see Microsoft Knowledge Base article 897615, Support policy for Microsoft software running in non-Microsoft hardware virtualization software.

Well as far as I knew M$ was only going to Supply

by OH Smeg In reply to Exchange 2007 32-bit to 6 ...

Exchange 2007 in the 64 Bit version except for the Trial Version which comes in the 32 Bit Version so it can be tested with the existing OS on 32 Bit Windows Server Application.

What M$ was recommending is to use the same Migration procedure to move for the Trial Version of Exchange 2007 as they supply for Exchange 2003 which is this

http://tinyurl.com/59a2sg

The 64 Bit version of Exchange allows for more users/mailboxes and bigger Mail Boxes which isn't possible on a 32 Bit System. Of course using a 64 Bit Application like Exchange 2007 requires a 64 Bit OS as well so you need to look at either Server 2003 64 Bit or Server 2008 64 Bit as the platform to Run Exchange 2007 on.
