Kernel migration from 720 to 721?

Hello Friends,

    Kernel version 720 is going to expire from 31st March 2015, So we need to move kernel version 721. Our environment is EHP4 FOR SAP ERP 6.0 / NW7.01, Kernel 720, Oracle 11.2.0.3 and Windows server 2003.

Most of the notes are available in SMP is related to kernel 721_EXT but i have not found any note to kernel 721.

Only the note i found 1726899 is quite related to kernel 721 upgradation steps.

For 701 to 720 kernel upgradation we fallowed the note 1636252 which has some different steps from the normal kernel upgradation.

For 720 to 721, What steps we have to fallow?

Please help us.

Thanks and Regards,

Farkath C
