Upgrade from ERP 5 to ERP 6.0 EHP 6

Hi,

I am dooing an migration/upgrade from ERP 5.0 on AIX Oracle to ERP 6.0 EHP 6 on Windows.

I did the migration from AIX Oralce to Windows 2003 MSSQL 2005 and now I need to upgrade to ERP 6.0 EHP 6.

SUM says that the OS (2003) and DB (2005) is not supported so my question is, how do I continue as ERP 5.0 is only supported on Windows 2003 MSSQL 2005.

Can I make a system copy (database backup/restore) to Windows 2008 MSSQL 2008 and with what tool.

What is the path?
