We have a MDS server running R80.10 and we're planning to upgrade it to R80.40, but there are some legacy R75.40 IPSO appliances (IP390 and IP690) managed by some CMAs.
I saw R80.40 documentation at section "Supported Backward Compatibility Gateways", but it was not clear to me, because I see that it can manage "Security Gateways" from R75.20 and "appliance Security Gateways" from R77.20.
If I understood well I would have no problem managing these legacy devices, because by "appliance Security Gateways" I think it means the ones mentioned at the document.
I just want to be shure before planning the upgrade with our customer.
Thanks!
