Hi, nice to get help with the deb package! I plan to go back to tag 0.4.0 and build new package that does

- automatic migration from simple to farm
- converts existing startup configuration to fits new startup script

that version should push to unstable repository. Next is then version 0.5.0 with scripts converting config file and checks startup configuration.

May be you can help by pushing it to the debian repository.

Thanks, Jens
