How to update from v1.6 to v2.0

Hello!

Generally, you don't need to uninstall v1.6. These are anyway conflicting
in all distributions I'm aware of.

If you have BIRD from package manager, use it.

Otherwise, you may want to remove the old binaries and maybe some PID file
or socket file, which depends on how you run BIRD.

The most difficult step is upgrading the config file as these are not 
compatible, yet quite similar. The most notable change is the channel concept,
see section 2.3 of docs:
