I just wanted to confirm that this was supported. The product advisor says I can, but the release notes for 4.4 state it works with Orion Core 2017.1, which is NPM 12.1. Which is correct?
It looks like the PUA is incorrect. You should upgrade to NPM 12.1 prior to upgrading VNQM 4.4. I will make sure this is corrected!
I personally don't 100% trust the Product Advisor. I've had it give me incorrect info in the past. Having said that, it doesn't mean that it is or isn't wrong here. If you want to be extra sure, you can toss an eval of NPM 12.0 onto a test machine you have somewhere and then install VNQM 4.4 and see what happens.
However, that's a lot of unnecessary trouble... Why not just update to NPM 12.1?? It's super solid and has a TON of fixes for some pretty big bugs that NPM 12.0 had... Just go look at the Release Notes for 12.1. It's incredible. You're gonna be running the config wizard anyways to install VNQM 4.4, so why not just install NPM 12.1, cancel out of the config wizard when it pops up, then install VNQM 4.4 and run the config wizard? It'll take you 5 extra minutes and you'll still only need to run the config wizard once.
The one and only problem we've run into with NPM 12.1 (and we have a large environment. 7 Additional Pollers and two Additional Web Servers as well as two VMAN collectors and a Netflow Database) is the new Virtualization Recommendation Engine service using up 9.5 GB of memory when it runs every night, but unless you have VMAN integrated with Orion I don't think this issue will affect you. If it does affect you just do what we did which is to turn off the Recommendation Engine for now until they release a hotfix for it...
Unfortunately, I don't have a test machine to be able to run those installs, so I have opened a ticket with support to see if they can clarify. The Advisor says its compatible, but the release notes state it runs on 2017.1. Interestingly enough, one of the bullet points on the release notes is that it now has the new UI, linking to a 2016.1 article.
That, and like I said in my original reply. There really just isn't any reason not to upgrade. 12.1 fixes a lot of bugs and is way more stable. Plus, perfstack rocks (other than not being able to use the perfstack charts in other views and reports. That is a pretty big bummer.).
