Shreeaditya asked a question.
i already have a Production environment of SNOW with all the three servers(Web server/ inventory server/ SQL database server. But i have received the Keys for Non-production Test environment. How to setup non production environment in snow license manager
This would come down to how you want to build the Non-Production environment.
If you want an exact replica of your Production environment then build the hardware the same, install the applications and once installed backup and restore your production DB's over the top of these new blank ones.
You can then apply the license keys in the Web Configurator.
You'll have no live data flowing in to the system but you would be able test patches etc. for that moment in time.
