KEA Migration Assistant Short Guide.

The KEA Migration Assistant (aka keama) is an experimental tool which helps to translate ISC DHCP configurations to Kea.

How to get last sources

From time to time the keama is upgraded for bug fixes, support of new or not yet ISC DHCP features or more likely support of new KEA features.

As now keama is included in ISC DHCP the most recent code can be found with the most recent ISC DHCP code in the master branch of the gitlab repository.

How to build and install

After the ISC DHCP build go to the keama directory and type:

make

To install it:

make install

Known limitations

keama uses a subset of the ISC DHCP configuration file parser with a lot of sanaity checks removed so it does not know how to handle an incorrect ISC DHCP configuration file and eventually can even crash on it.

ISC DHCP and KEA have different models for many things, for instance ISC DHCP supports the failover protocol when KEA supports High Availability. In some cases keama tries to cope with that, for instance for host reservations which are global in ISC DHCP and by default per subnet in KEA.

How to use

The manual explains how parameters guide keama choices for lifetimes, name literals, host reservation scope, etc. Directives were added to the ISC DHCP syntax (they are valid but ignored) for options.

Each time keama finds a feature it can't translate it emits a comment with a reference to the feature description in a kea (not isc dhcp) gitlab issue in the "ISC DHCP Migration" milestone. The number of reports is returned by keama when it exits.

How to help

If you have configuration patterns you would like to see supported by Keama please feel free to reach out to us. We are always looking to improve the tool.
