nworks MP 5.6 is necessary (technically 5.5.2) in order to manage that vSphere 4.1 Inf. nworks MP 5.6 will also work fine with the VI 3.5 Inf. Looks like you will be doing an upgrade to nworks MP 5.6. For this nworks 5.6 Infrastructure, we recommend Windows Server 2008 R2 (but do not require this) to run as your collectors. In most cases, you will be looking at a parallel installation of nworks 5.6. The final "cut over" is when you Install the nworks MP 5.6 MP within the SCOM environment. To do this you will need to:
1.) Export override MP's
2.) Delete the 3.6 MP
3.) Import the 5.6 MP
4.) Import the override MP's
As for their override MP's, it should be able to import directly over 5.6. However, many discoveries, rules, and monitors have either been added, removed, or changed since nworks MP 3.6. An example of this is that most performance Monitors in 5.6 use multi-state thresholds. Where as in 3.6 these did not exist. What you will see are overrides trying to target a property called, "Threshold" while in MP 5.6 there are two called, "Threshold 1" and "Threshold 2". Since "Threshold" does not exist, this override will more than likely not function at all. I would recommend documenting the overrides, compare them with the default Monitor settings within MP 5.6, and then have a discussion with the customer. I would wager to bet that a good chunk of those overrides will not be necessary with all of the improvements that have been made over the time within the nworks MP for VMware.
Hope this helps!
