Netweaver Gateway 2.0 Installion option
I have some question regarding Netweaver Gateway Installation
Question 1) I have to Install Netweaver Gateway 2.0 for our solution manager 7.1 SP3.
I want to know, Can I deploy Netweaver Gateway Add-ons on my solution manager ABAP stack (7.1 SP3, I will upgrade to latest SP level) or I have to Install seperate box based on:-
1) SAP EHP1 FOR SAP NETWEAVER 7.0
2) SAP EHP1 FOR SAP NETWEAVER 7.3
3) SAP EHP2 FOR SAP NETWEAVER 7.0
4) SAP NETWEAVER 7.0
5) SAP EHP3 FOR SAP NETWEAVER 7.0
and on top of that I have to deploy add-ons?
Question2) Just wondering whether I can deploy Gateway add-ons on Netweaver 7.1 or Netweaver 7.1 EHP1.
Question 3) If I have to Install on seperate box than does that installtion has to be done as Dual Stack or only ABAP Stack.
Waiting for usefull comments..
