It would be great if you could update multiple records at once. ie. changing secondary servers adding a new NS record to all the domains obviously it's trivial if ispconfig is not used, because you can yse all the command line tools for mass replacing. Unless there is an easier way I don't know about ? Thanks, Richard
Replace such things via phpMyAdmin by an update command and then resync the dns zones through the ISPConfig panel. It's the fastest way to do something like this.
I would do the same thing too. I also hope soon there will be a resync script that can be utilized without having to do it via ISPConfig web control panel.
