'Can we have two instances of Rundeck installed on same server?
I have rundeck 3.3.10 installed on my RedHat server , I want to upgrade to 4.0.1 community version.But I want to keep the older version intact, while I install and setup the latest version. Is it possible ,if yes what are the steps to achieve this ? I checked on PagerDuty site but couldnt find the information i was looking for.

You can keep two instances in this way:
The first one installed from the RPM/repo listening to the port 4440 and the second one could be installed as a WAR (for example, in the /opt/rundeck directory) and listening to another port, e.g: 4441.
You can see in this answer how to configure the second instance.
But if you're looking to keep two RPM instances, the best way is to replicate the 4.0.1 upgrade in a virtual machine (like Vagrant) and later upgrade your main server.
NOTE: Don't connect both instances against the same database, I assume that you're creating a specific database for the 2nd instance.
