I saw ISPConfig goes to 126.96.36.199, so I want to upgrade it. But I saw that 3.0.2 start to use bind DNS instead myDNS. So, is it a must to resetup all records from admin page? there's no any upgrade path? And, is there any big change that I need to be careful of the upgrade? maildrop and dovecot? Actually I use all server functions of ISPConfig. Thanks.
