This is the 2nd 'developer preview' edition of Couchbase Server 2.0.
Installation and Upgrade
It is not possible to perform an upgrade between Couchbase Server 2.0 pre-releases including beta, or to perform an offline upgrade from Couchbase Server 1.8 to a pre-release or beta of Couchbase Server 2.0. To upgrade between these versions use cbbackup to backup your data, delete the existing installation, install the new version, and restore the stored data.
Documents identified as Non-JSON stored within Couchbase Server may appear as binary, or text-encoded binary data within the UI.
During periods of moderate CPU load on the Couchbase Server
cluster, you may see warnings that
IP address seems to
have changed. Unable to listen to node X.X.X.X.
The cbbackup, cbrestore,
and cbtransfer command-line tools require the
zlib module for Python to have been
installed. If Python was installed from source, you must have
zlib using the
--with-zlib option during the build process.
