Re: Migration to 64 bit
A quick summary:
- 32-bit legacy mode = 32-bit drivers & 32-bit applications - plain & simple, all runs 32-bit
- Compatibility mode = 64-bit OS & 64-bit drivers ONLY - support for both 32-bit & 64-bit apps (same 32-bit apps may require a 64-bit update though)
- Full 64-bit mode - 64-bit, 64-bit drivers & 64-bit apps required - no support for legacy application.
You would need to migrate your OS to Win2K3 64-bit & Exchange 2000 to 2007 to get 64-bit funcionality. Bear in mind, however, that Exchange 2007 is in beta testing now & (hopefuly) will be released as a production version next year.
Rgds.

Re: Migration to 64 bit
Thanks very useful previous input - apologies my naive questions. So I have a 32 bit OS running in legacy mode (and lets say Exchange 2003). If I want to upgrade to 64bit compatability mode, do I have to start from scratch, clean build, restore exchange etc or is there a windows upgrade route?
Then if I want to migrate to 64bit exchange and 64 bit Native mode, I presume I uninstall exchange. Can I change the HAL in flight (ie amend the boot.ini)? Then install the 64 bit exchange version and restore the database.
It's this nitty gritty I want to understand in order to plan. Again any references to documentatin either HP, MS or elsewhere warmly welcomed. Thanks.

Re: Migration to 64 bit
In your case it shouldn't bother you as you need to change your hardware anyway.
Re Exchange 2000/2003 => 2007 - you can find some info there:

I think though that the small print says you migrate just your data to a new installation of Exchange 2007.
Rgds.
