Ensure an Existing OpenROAD 5.1 Test Environment Exists
Most live production systems already have a fully defined test area; you may clone this area for an OpenROAD 5.1 test environment. Or you could clone an active client environment.
Note:  Do not clone a development environment. Experience has revealed that starting with a development environment wastes much time and effort during the upgrade. Reasons for this typically involve disparities in the environment settings and the application source code between the development and the live environments.
