SAP Migration - homogenous or heterogeneous?

Dear all,

We are planning to perform SAP 4.7 server migration from Sun Solaris/Oracle to HP-UX/Oracle.

Below is the detail of source system:

Operating system: SunOS 5.9 Generic 117171-12 Sep 2004

SAP kernel release: 640 with patch level 104


Target system:

Operating system: HP-UX 11

RDBMS: Oracle version 9.2 or 10

Do we have to perform heterogeneous system copy (database export/import) or we can do it with homogeneous system copy - Oracle specific procedure (database backup/restore)?

Please kindly advise.

Best regards,
