This question came from our site for professional and enthusiast programmers.

If you have any 3rd party components, such as web parts, make sure that they are not limited to 32bit operating systems.

In our environment, we upgrading a x86 WFE server to a x64 server. Although we did not upgrade to Windows Server 2008, it may be comforting for you to know that we didn't encounter any major issues with regard to x64 compatibility.

The main hurdle was ensuring all of our custom application code was recompiled to x64. Also bear in mind that you will need to ensure all servers at a particular tier (e.g. WFE, application, DB) should be of the same architecture (i.e. x86 or x64).

I'm not sure if it will be useful to you, but I have recently posted instructions on how to go about upgrading an x86 SQL server running server 2003 to an x64 server running server 2008. Check it out at if you are interested.

I would be interested to know if you encounter any issues - HTH.

Cheers, Ben.
