Upgrade AIX OS for existing SAP ECC 6.0

Hi,

We have an SAP system(ECC 6.0) running on AIX OS (Version 5.3). We are planning to upgrade our system os to AIX 6 or AIX 7 versions.

So inorder to upgrade do i need to have any changes to my SAP system? Can i run my existing SAP smoothly without any issues with the upgraded AIX.

Kindly suggest me the changes to be done or to be followed for running SAP.

Regards,

Dilip
