We want to upgrade our windows version to Enterprise 2008 64 Bit.

Please let me know how to proceed with this ? How do we prepare the system to continue this upgrade without uninstall SAP

Thank you

There are ways of doing in-place upgrades (see Note 1494740 - SAP system migration from Windows 2003 to 2008 (R2) 64-bit) but since the hardware drivers changed from 2003 to 2008 you may have a hard time getting the system back up after you do an in-place upgrade.

I would do a homogeneous system copy, that's the safest way.
