64-Migration / Systemcopy / fastest way
we need to migrate a ERP 2005 / BI from 32 to 64 Bit.
Sourcesystem: - Windows 2003 32 Bit - Oracle 10.2 - SAP SID: DR1 - Oracle SID: DR1 Targetsystem: - Windows 2003 64 Bit (maybe Windows 2008 64 Bit) - Oracle 10.2 - SAP SID: P10 - Oracle SID: P10
I've a very small time frame... max 3 days. A system copy with export / import will running longer than 3 days... I think 5 days with post system copy tasks.
Is there a other method to copy the system faster? What is the fastet way?
