Can I still use 32 bit versions of Windows or SQL Server?
No, it is no longer allowed to use 32 bit versions of Windows or SQL for modern SAP releases and it is strongly advised to upgrade all 32 bit versions of Windows to 64 bit immediately. Any hardware sold in the large 5 years is 64 bit capable. It is not supported to upgrade from Windows 32 bit to Windows 64 bit “in place”. Neither is it supported to upgrade from Windows 2003 to Windows 2008/2008 R2 “in place”. In both these cases a “Homogeneous System Copy” must be performed. This is a very simple procedure for SQL Server customers.
