Check out the Product Upgrade Advisor which can help you answer all of your upgrade questions! and install trial version on test server and add some samples from your environment to check compatibility with your current environment than upgrade on production servers.
Hi there! Here are the requirements for NPM 12: NPM 12.0 and Orion 2016.1 system requirements - SolarWinds Worldwide, LLC. Help and Support Note: These requirements consider you use every feature NPM has to offer, for best performance.

For scalability, we do have updates, see below.
SolarWinds NPM Scalability Engine Guidelines
Stackable Pollers Available?
Yes. Up to four total polling engines may be installed on a single server (i.e. one primary polling engine with one to three additional polling engines, or four additional polling engines on the same server).
A stack requires only 1 IP address, regardless of the number of APEs.
Poller Remotability Available?
Yes, for SolarWinds NPM 10.4 and later
Poller remotability is a feature that enables the local storage, using MSMQ, of up to ~1 GB of polled data per poller in the event that the connection between the polling engine and the database is temporarily lost.
Primary Poller Limits
~48k elements at standard polling frequencies
25-50 concurrent Orion Web Console users
SNMP Traps: ~500 messages per second (~1.8 million messages/hr)
Syslog: 700-1k messages/second (2.5 - 3.6 million messages/hr)
One polling engine for every ~12k elements
Maximum of 100k elements per primary SolarWinds NPM server (i.e. 1 NPM server + 9 APEs).
WAN and/or Bandwidth Considerations
Minimal monitoring traffic is sent between the primary SolarWinds NPM server and any APEs that are connected over a WAN. Most traffic related to monitoring is between an APE and the SolarWinds Orion database.
See "Orion Server Hardware Requirements" in the SolarWinds Orion NPM Administrator Guide.
