Before You Upgrade

If you are planning an upgrade from SecurityCenter 4.x, due to the many enhancements and changes made in the SecurityCenter 5 solution, Tenable strongly encourages you to install and test the latest version of SecurityCenter in a pre-production environment prior to upgrading in your production environment to ensure the new workflows and enhancements are compatible with your current workflows.
