I'd like to upgrade an existing server to 64-bit.Microsoft made this easy with Vista, but I have a feeling that that's not the case with Server 2003 (Standard R2.) For one, it's an OEM install on a HP server and I assume would normally need an OEM install CD to match the key.Can I do this? Anyone know where I'd get the software?

Hiya chap, unfortunatley Windows Server 2003 x32 to x64 is a rebuild - there is no supported in place upgrade path - especially if Exchange 2003 is installed on the server. Cheers A

It's just been a file server with SQL for a couple years. Reinstalling from scratch shouldn't be a problem. Unless you're saying that because it's a rebuild, Microsoft wants me to buy the software all over again.

Hi, Please understand that we mainly discuss Exchange issues in this forum, I suggest posting this issue in Windows Server 2003 newsgroup: http://technet.microsoft.com/en-us/windowsserver/bb841405.aspx Thanks, Elvis

Thanks for the link. I honestly couldn't find it starting at support.microsoft.com.
