since 2.0 there is more to this than copying the dbname.couch file around. For one thing, every database is now sharded, so you have several .couch files to copy (even if you only have one node). So make sure you've copied them all and kept their directory hierarchy. In addition there is a meta database called '_dbs' which is how couchdb knows where the shards of all databases are. In your old install, you will have a document in _dbs database named after the database you copied. You'll need to copy it to your new cluster and modify the node names embedded in the by_node and by_range attributes (assuming your new machine _has_ a different name. if they're both 'couchdb@127.0.0.1' you won't need this step).
We recommend replication as the means to move data from one couchdb instance to another rather than moving database files around by hand.
