Yes I have participated, we need to follow the following steps in my point of view
Preparation & Planning : What kind of system/technology was supposed to run on what kind of machine
The specifications regarding the clustering of systems
How all these stand-alone boxes were going to talk to each other in a foolproof manner
Production setup should be documented to bits. It needs to be neat, foolproof, and understandable.
It should have all a system configurations, IP addresses, system specifications, & installation instructions.
It needs to be updated as & when any change is made to the production environment of the system
