Hi John,
There is no upgrade path from Zenoss 4.2.5 to either 5.x or 6.x.

I would seriously question whether you want to go there????

Zenoss 5 / 6 is a very different animal.  If you already have Zenoss 4.x skills then managing a later version is very hard and very frustrating.  It also takes hugely more hardware resources.  Other factors depend on the size of the estate you are monitoring and any requirement for high availability of your monitoring.  If no HA and around a 1000 devices or less, I would say stay with your 4.2.5.  If it doesn't have the latest update (SUP732) then I would apply that.

Cheers,
Jane

I'm with Jane. Zenoss 6, especially, has been flakier than a box of breakfast cereal, and it just seems to get more so with each release. Version 4.2.5 for us was rock-solid, and we had it customized - reliably - to the point where a server couldn't sneeze without us getting alerted. 

Version 6.1.1, on the other hand, can't even get us performance metrics reliably; every half hour we get data collected followed by two hours of NaN values, and that's after several in-place upgrades from version 5.1. Can't collect event logs reliably. Can't collect performance metrics. Powershell processes on servers randomly consume 100% CPU. Seriously, stick with 4.2.5 if you're already running it.
