Version 2.0.0 is installed as a separate package called "couchdb2". When setting the config option "package" attribute to pkgs.couchdb2, a corresponding service configuration will be generated. If a previous 1.6 installation exists, the databases can still be found on the local port (default: 5986) and can be replicated from there. Note that single-node or cluster setup still needs to be configured manually, as described in http://docs.couchdb.org/en/2.0.0/install/index.html.
