Extended Configuration Syntax and Options
The BIND 9.2.0 configuration is similar to BIND 8.1.2; however, there
are a few new areas of configuration, such as views.
You can modify a BIND 9.2.0 configuration file to get a BIND 8.1.2
configuration file. However, you must check complex configurations to
identify if you can implement them more efficiently using the new BIND
9.2.0 features.
You must convert BIND 4.9.7 configuration files to the new format using
the /usr/bin/named-bootconf.sh shell script.
