Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have a production server, that is used for MS SQL Server Databases.

The machine specs are: - Intel Xeon E5410 CPU with (EM64T) - 4 GB RAM - SCSI HDDs in RAID mode

It currently has: - Windows Server 2003 R2 Enterprise Edition Service Pack 2 (32bit) - SQL Server 2005 (9.0.3080) (32 bit) as the default instance. - SQL Server 2008 (10.0.1600) (32 bit) as a named instance "SQL2008".

I need to upgrade the SQL Server 2008 instance to 64 bit. How do I do this?

I know that the OS needs to be 64 bit mode too. Can I do a upgrade of windows to Windows Server 2008 R2 64 bit first or?

You'll basically need to make a back up of the existing databases, then rebuild the server using Windows Server 2008 R2 and install SQL Server 2008 x64. Windows doesn't support changes in the bit-ness of the OS when performing an upgrade; no 32 bit upgrades to 64 bit.
