Is there a guide on how to migrate from Server 2003 32bit to Server 2008 64bit?

Do not follow this procedure if any of the following are true:

• Backup Exec is clustered.
• The Backup Exec Shared Storage Option (SSO) is installed.
• The Backup Exec Server Free Option is installed.
• The computer where Backup Exec is installed and the computer where it will be installed are running two different versions of the Windows Operating System.
• If planning to move Backup Exec to a different drive/directory on the server.
• If upgrading from one version/revision (build) of Backup Exec to another.

I followed that guide and it never caused any issues. I migrated from Windows Server 2003 x32 to Windows Server 2008 R2 x64 without hassles.
The BIG thing is to make sure you have a copy of your catalogs and your database (Catalogs/Data folders) BEFORE doing anything.
