hi all

i want to update PCS7 v7.1 to v9.1

According to the guide published by Siemens, I must first update "V7.1" to "V7.1 SP4" and then update from "V7.1 SP4" to "V9.1 SP1"

I don't want to install "v9.1 sp1" and want to continue with "v9.1" without "sp1" on my PC.

if i want to use manual about update "v7.1 sp4" to "v9.1 sp1" , can i have "v9.1" on my PC in spite of "v9.1 sp1"? 

please help. thank you
