Because your data is important, you should create a test environment for Insight. It is essential for the initial phase of setup and configuration, as well as for testing all custom modifications that you might make on site or request from Cyncly Professional Services.
How you set up a test environment depends on how you will use it before, during, and after you migrate your system to Insight. This could involve buying extra hardware. The Cyncly can assist you in making these decisions.
