Part of the technical setup of an ERP implementation enviroment includes setting up the DEV, TEST and LIVE environments.

DEV - the development environment, mostly used by your development partner(s)

TEST - the testing environment mostly used to test CR deliverables and for UAT

LIVE - the live/production environment that you will actually use when you go-live

These environments are isolated from each other with their own code set and database.

You should expect to frequently update one from the other, for example to move code from the TEST enviroment to the LIVE environment. You should also expect that there will be a cost to the project for the initial technical setup of these environments.
