Dear Experts,

My Self SAP R/3 4.0B who was supported by Solaris 5.1 and Oracle 8.1. We have been together for a long time supporting each other to full fill the requirement of our co-workers. But now i am looking for change and growth in the valley of SAP. During the time i have read the below phrase and decided to have a change!!!

                                              

                                                             Change is the law of life.

                              And those who look only to the past or present are

                                               certain to miss the future.

      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.

      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.
