Is this internal DNS or external DNS - does the DNS server automatically update with local A records when new DHCP addresses are issued?

You could be using DNSMasq (http://www.thekelleys.org.uk/dnsmasq/doc.html)  or you could be using BIND, so it's important to understand what you have before attempting to migrate!

Both Dnsmasq and Bind have webmin modules, so can you advise which you are using?

You can find out which is issuing DNS by using

sudo netstat -auntp | grep 53

Then you should be able to just install bind (sudo apt-get install bind9), copy the bind config file (which should be /etc/named.conf) and any includes /etc/named.conf.include/

Check in the named.conf file for the location of your zone files and copy those over to the same location on the new server.

If you have IPTables running on the new server (or UFW) you should also do a

sudo ufw allow 53.
