New to RockNSM - advice on upgrades



I have a been using Zeek (Bro) on Security Onion and Ubuntu for quite a while and recently came across RockNSM. Still trying to get my bearing on where things are at in terms of config/etc for tweaking and other items.

Have a couple of sensor deployed on version 2.2 and was trying to determine if there is an easy upgrade path to 2.4? I would like to upgrade in place sense I have a 2-3 months of data on the sensors.
