Hi RB ,
As per your below note.
1443424 - Migration path to Win2008/MSSQL2008 for 4.6C and 6.20/6.40
- Upgrades running on Windows Server 2008 (R2)/SQL Server 2005 as well as upgrades running on Windows Server 2003/SQL Server 2008 (R2) will not be supported.
The upgrade must be started immediately after the system migration. The system must not be used productively until you reach the end of the upgrade downtime.
The instructions documented below should be performed on the migrated system running Windows Server 2008 (R2) and SQL Server 2008 (R2).
I clearly mentioned the above point In my first posting .
Thanks
Siva
