Upgrading ST-A/PI 01N_700ECC (SP-0001) to 01Q_731 in IDES EHP6 ERP 6.0

Hello Experts,

In our ECC 6.0 EHP 6 IDES system we have ST-A/PI      01N_700ECC . But when i run RTCCTOOL in SE38 it is asking to upgrade to ST-A/PI   01Q_731.

I am little confused how can i do it?

1.  Whether i have to upgrade to  01N_700ECC to get ST-A/PI   01Q_731 through SPAM.

Or

2. I have to install new add on ST-A/PI   01Q_731  through  t-code  SAINT .

Kindly help me to resolve this
