High Availability installation

Hi Experts,

We have the following server requirement for our customer and go live planned in phases

SAP SRM,

SAP Netweaver Portal

SAP MDM

SAP PI

In Phase 1, We are planning to go live with UAT System (considering UAT as PRD), becoz in phase 1 we are going live with limited functions and less number of users.

Later in Phase 2, we are planning to with the following options

a. Migrate all Phase1 data to PRD Server

b. Install PRD Server with HA Setup

My Questions

a. Will it possible to convert my UAT to PRD (distributed installation to HA)

a. If (a) is not possible, What will be the best approach to migrate Phase 1 UAT data to PRD

b. In HA Setup Can I install SRM, MDM on same Server. Is this the best approach or do we need to go with separate box for each.

Regards
