SAP Lumira for Clustered BI Platform

I have been searching through different forums, but could not get the direct answer.

Currently, i have two separate BO nodes installed in clustered environment. BO 4.1 SP6 installed completely on each node with Tomcat.

T01- installed BO 4.1 SP6 with tomcat- windows 2012 server 64 bit

T02- installed BO 4.1 SP6 with tomcat - windows 2012 server 64 bit

both nodes pointing to same Audit db, and FRS folder (on shared network drive).

sharing one CMS and cluster key.

Then a DNS link with load balancer pointing to both of them (http:// BOETEST)

Now if i want to add Lumira server as a seperate node i have few questions:

1- I will be installing ( SAP Lumira server for BI Platform 1.30 Windows (64B), correct?

2- SAP Lumira, Server for BI Platform blog is talking about SAP Lumira Add On, do i have to care about that?

3- all the other services requires (RESTFUL, WACS, Scheduling, Processing) do i need them to installed on Lumira server or NO?

4- i assume, during installation it will ask for CMS name and port, i am sure to use same CMS name, which port i will be using?

5-After installation, do i have to apply some other changes on actual BO server through CMC?

6- Do i have configure windows AD setup also on Lumira Node? or it will work through BO servers?

7-Last- in case of upgrade or patching, do i need to patch it together with other BO nodes, or do it alone.

Thanks,
