(NNMi) Support Tip: Deploying a Test environment to minimize Production downtime
With the NNMi Premium and Ultimate Editions are a set of Non-Production (NP) licenses that can be used to deploy a Development and Test environment and run it in parallel of the production one.
It is recommended to deploy a Test environment mirroring as much as possible the Production environment and use it to validate any changes prior to applying them on the Production environment.
This is the best approach to minimize the Production downtime and allow a smooth upgrade of the Production environment to the next version.
