Hi: What are the necessary files to backup and restore if one needs to migrate from the server with ISPConfig3 with Apache2 and powerDNS to another new server freshly installed with ISPConfig3 (nginx) and BIND9? Migration route: ISPconfig3/Apache2/poweDNS --->> ISPConfig3/nginx/BIND9 The old server is running Debian Squeeze and the new one Debian Wheezy. Thanks! PS: Posted this to wrong section earlier. Sorry!
