You can have the manager's installer run a readiness check to make sure your environment is ready for the Deep Security Manager installation. Nothing will be installed but the installer will check your installation environment to make sure it complies with system requirements. It will then generate a report which you can use to fix any issues before actually installing Deep Security Manager. For example, you may need to free disk space, allocate more vRAM, or install a new OS. If you're not ready, you can cancel out of the installer and return when ready.
