For a project I was looking for a document about migrating from Windows 2003 Small Business to Windows 2008 R2 and Exchange 2010. I’ve found a great article written by demazter, this article describes every step. Original link: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2881-Migrate-Small-Business-Server-2003-to-Exchange-2010-and-Windows-2008-R2.html 

This guide is intended to provide step by step instructions on how to migrate from Small Business Server 2003 to Windows 2008 R2 with Exchange 2010.

For this migration to work you will need the following software:

Steps required:

It’s important that the steps are followed in order as different stages make different changes to the way in which your server operates.  For example you MUST make the 2008 server a domain controller before you install Exchange.

Deployment Image Servicing and Management (DISM.exe) is a new command line tool that you can use to service a Windows image or prepare a Windows PE image. The DISM tool replaces the Package Manager (pkgmgr.exe), PEimg, and Intlcfg tools used with Windows Vista. DISM consolidates the functionality found in those three tools, as well as delivers new functionality to improve the experience of offline servicing.

• Add, remove, and enumerate packages and drivers.
• Enable or disable Windows features.
• Apply changes based on the offline servicing section of an unattend.xml answer file.
• Configure international settings.
• Upgrade a Windows image to a different edition.
• Prepare a Windows PE image.
• Take advantage of better logging.
• Service down-level operating systems like Windows Vista with SP1 and Windows Server 2008.
• Service all platforms (32-bit, 64-bit, and Itanium).
• Service a 32-bit image from a 64-bit host and service a 64-bit image from a 32-bit host.
• Make use of old Package Manager scripts.

HP released an Sizer tool for Microsoft Hyper-V 2008 R2. Source : http://h71019.www7.hp.com/ActiveAnswers/us/en/sizers/microsoft-hyper-v2008.html

The HP Sizer for Microsoft Hyper-V 2008 R2 is an automated, downloadable tool that provides quick and helpful sizing guidance for “best-fit” HP server and storage configurations running in a Hyper-V R2 environment. The tool is intended to assist with the planning of a Hyper-V R2 virtual server deployment project. It enables the user to quickly compare different solution configurations and produces a customizable server and storage solution complete with a detail Bill of Materials (BOM) that includes part numbers and prices.

The HP Sizer for Microsoft Hyper-V 2008 R2 allows users to create new solutions, open already existing solutions, or use other types of performance data collecting tools, such as the Microsoft Assessment and Planning tool (MAP), to build rich Hyper-V R2 configurations based on HP server and storage technology. The tool allows rapid comparison of Hyper-V R2 characterizations using various HP server and storage choices.

Customers often ask “Given a hardware load-out X, how many Ys can I get/run/host?”

The frustrating answer always starts with “…it depends…”. We caveat this way not because we want to frustrate, but because it is true. Many teams will go on to say “We have tested the following in our labs and gotten the displayed results…”

1 X = thingy

2 X = more thingies

3X = many more thingies

While accurate, not super-helpful.

The truth is that to do good perf planning for Hyper-V you have to run some tests.

Run them using your actual production load (converted to Virtual Machines) in a test environment.

TIP: you can download the free VHD version of SCVMM, then run it as a VM to convert your production machines to “test” virtual machines.

Then play with your assumptions and tweak things higher and lower and to your design tolerance and actually observe how perf goes.

Add an overhead/forgot-to-test percentage, done.

Last week I posted an articel about running the vSphere client on a Windows 7 workstation. This was a problem, but now after Update 1 for vSphere Windows 7 and Windows 2008R2 are now supported.

One of the great things about the Vista and post-Vista operating systems is that the installer subsystem allows you a great deal of flexibility when it comes to installing multiple operating systems. It is fairly easy to put together a single installation DVD or USB stick that will allow you to install Vista, Windows 7, Server 2008 and Server 2008 R2 – in a variety of x86 and x64 flavors.

A couple of things to note about this guide:

• I do not use Vista — I have never really used Vista and now with Windows 7 out there really is no reason to; however the steps here will work just fine with Vista installation sources
• I have only tested this using a USB stick and will only cover that method here – it’s much more flexible (and faster) for installation than using DVD — but DVDs should work just fine: you can find plenty of tutorials on the web that will tell you how to use oscdimg.exe to take the files we create here and turn them into a burnable ISO

 WHAT YOU WILL NEED:

• USB stick, at least 4 GB (perhaps larger depending on how many OSes you plan to integrate, I use a 16 GB) that has been properly formatted using Steps 1 and 2 here
• ISOs or DVDs of the operating systems that you plan to integrate
• imagex.exe (can be found for download on the web, or you can download the full 1.7 GB WAIK here)
• computer running Vista or newer operating system (XP should work but I have not tested it)

Windows 7 and Windows 2008 R2 have a really useful feature called “VHD Boot”. With that you can boot your entire Windows out of a Virtual Hard Disk file (as those used with Virtual PC or Virtual Server).
