Note  For ESXi 7 and 6.7, users must use the v8.5.4 OVA file to create a new VM. Versions 8.5.3 and earlier will not deploy and are not supported on ESXi 7 or 6.7.

Important  Although a version 8.0 and later Security Manager can allow an earlier version appliance (e.g., version 7.8.4) to be added on the Email Appliances page, the management settings for that appliance are read-only and cannot be modified. For optimal system efficiency and performance, we strongly recommend that manager console and appliance versions match.
