Hey there, in my multiserver setup I have one really old installation, the ISPConfig Panel Server holding the master database and my primary DNS service. Now I would like to move only the panel and master database to another datacenter for failsafe reasons and reduce the old server to a pure bind DNS service. Well, on every slave server I think it shouldn't be so hard to grep out the masters DNS name or IP and change it. I also don't think it will be a problem to setup ISP on the new panel and migrate it with the old master DB, annoying but not too hard. But what do I have to change on the old DNS server in order to change it from a master-db to a slave server that polls the new master DB? And what are the PHP Libs that are minimum required to run an ISP slave that doesn't server websites?
