Raised a separate topic for 6.12.65-31 not being available in http://downloads.freepbxdistro.org/ISO/ at 6.12.65-31 not available in old version distro downloads for the purposes of backing up live install of FreePBX and installing a fresh copy of FreePBX with the backup made from the live system (Please see Bob’s post above suggesting this). I will report back once I receive an update on the other topic.
