    I will use the dns server to reduce the nameserver cache time. I suppose to have to reduce the TTL to somthing like 600 maybe 3 day befor the moving day. It is nessesery to edit all records (A MX )one by one or only to edit the TTL from the DNS Zone?
    And what does the TTL for the NS record say?

    TTL does not change

    I don't understand why mydns does not change the TTL which I've set to 600. If I look in the ISPConfig mydns frontend it say a TTL for alle reccords set to 600. But when dig is used local or remote it show a TTL with 1d and not 600 secounds. There ist no firewall. But what else could be wrong that the TTL does not increase?
