Convert a single server Opennebula setup into clustered + separate front-end setup

I have a single server setup that contains sunstone, node, and system/image datastores in the same machine.

I am planning to separate out the pieces:
Front-End on a different server, different subnet even (For Failover).
Default SSH driver so nodes use local storage.
The single server that is currently running should keep all the VMs intact (including volatile storage attached)

What is the best approach to this? I intend to backup all the images(system or otherwise) before proceeding.

Hello Amit,

Were you able to implement your plan?
If yes, could you share what steps you followed to have that working?

Thank you,
