We are attempting to migrate some old DNS/Mail servers over to a multi-server ISPconfig 3 setup. I've run into an issue with migrating the DNS servers though. I've tried copying the bind config files over but that doesn't seem to work and I've also tried to import a zone file from the old server. The import is successful but the information appears incomplete and the 'records' tab gives a 'Zone format is invalid' error. Has anyone successfully migrated Bind to ISPConfig 3? All ideas welcomed!
