Switching from Stand-Alone to a Server Cluster Configuration
I would like to switch a Stand-alone PPM environment to a Server Cluster Configuration, in order to isolate PPM services from users requests. But I have some doubts:
1. Is it possible? Or should I install PPM from scratch and reconciliate the DB? I saw the manual (PPM 9.30 - Installation and Administration Guide - Document Release Date: November 2014). At Page 203 I find a chapter called "Switching from Stand-Alone to a Server Cluster Configuration" and I understand that it's possible. But at page 31 I read "You can configure a server cluster that has just one node. The difference is that you can add nodes to the "server cluster" while you cannot add nodes to a stand-alone instance."
2. Do I need an external Web Server? Or is it not necessary as I don't need load balancing (one cluster for PPM services one for users requests)?
