Hi Ashutosh,
At a very high level, I would save the first migration and upgrade to 4.6c on the current box. Unless PAM says otherwise.
Regards, Juan
Dear Juan,
Thank you juan for the valuable suggestion 🙂
I have gone through PAM and sapnotes 156548 - Released operating systems SAP kernel 4.6x ORACLE (version 120 of the sapnote)
which has not said anything regarding the solaris 5.1

I think you should be able to upgrade the existing system to R/3 4.6C on the same hardware. Check the SAP note 335690 - Special Support of DB & OS releases for SAP upgrade/installa. If yes, then you should upgrade the system first and then migrate it to new hardware and upgrade DB to 11G and finally upgrade SAP to EHP7. It should be possible to migrate the system to Oracle 11G directly instead of to 9i, I have done it but it needs some extra work. If your system is non unicode then consider unicode conversion.

Your source is non-Unicode. So please mind to migrate to Unicode as well.
