Currently we have the a tutorial that talks about updating current deployment to a secured environment but it's missing a few things:

• does not highlight that this requires down time (should be very clear)
• it's not currently complete since it just focus on the individual node and not in the set of nodes
• we should differentiate the actions to be done on a shard from the replica set since it requires different treatment
• ends with creating of application users but I believe that we need to explicitly highlight the steps on the replica set (ex: bring all remaining nodes of the replica online ...)
