Migration overview

The McAfee® Advanced Threat Defense 4.0 is optimized for improved performance and enhanced security. This migration guide helps you upgrade your McAfee® Advanced Threat Defense Appliance software to 4.0. Upgrading to Advanced Threat Defense 4.0 is different from the previous Advanced Threat Defense upgrades. For this release, you are migrating your appliance because as part of the process, the operating system (OS) of your appliance is upgraded along with the Advanced Threat Defense software. During the migration process, all your data and configurations are backed up, followed by OS installation, data restoration, and installation of the Advanced Threat Defense 4.0 software.
