Hi Carla,

Yes, these steps are possible with SQL Server and SAP.

I have performed this upgrade successfully.

Subject: [sap-basis] Windows 32-bit to Windows 64-bit path?

My question is: Can I go directly from Windows 2000 32-bit to Windows 2008, sp2 64-bit and upgrade SQL Server 2000 sp 4, 32-bit to SQL Server 2008, 64-bit and running SAP ECC 6?
So my steps would be:

Create a new server with Windows 3008, sp 2 64-bit. Install SQL Server 2008, sp 2. Upgrade the database by using backup and restore (or detach/attach). Then point the application servers to the new database instance.

Downside: Amount of downtime needed
Plus: We have a fall back database immediately available and I do not have to have additional downtime for stopping at Windows 2003, or at 32-bit, or at SQL Server 2005.

I know that the Microsoft products can support this shortcut. Can SAP? This is where I am uncertain because of all the conditions for Netweaver, Central Instance, etc?

Any feedback is greatly appreciated.
Carla
