Performing the Single Node Upgrade
To upgrade a single Couchbase Server node, back up your data and then install the upgrade package.
Use the cbbackup tool to back up your data.
- Download the Couchbase Server package.
- Back up the cluster data.
- Back up the server-specific configuration files. While the upgrade scripts perform a backup of the configuration and data files, make your own backup of these files as best practice. The configuration files are found in /opt/couchbase/var/lib/couchbase/config/ by default.
- Stop the Couchbase Server service.
- Check your host name configuration. If you have deployed Couchbase Server in a cloud service, or if you are using host names rather than IP addresses, you must verify that the host name has been configured correctly and is resolvable before performing the upgrade.
- Perform the upgrade installation for your platform; see the section Installing Couchbase Server appropriate for your platform for detailed installation instructions.
