Finally, as new versions of VoltDB become available, you will want to upgrade the VoltDB software on your database cluster. The steps for upgrading the VoltDB software on a database cluster are:
Place the database in admin mode (voltadmin pause).
Perform a manual snapshot of the database (voltadmin save).
Shutdown the database (voltadmin shutdown).
Upgrade VoltDB on all cluster nodes.
Start a new database using the voltdb create option, your existing application catalog, and starting in admin mode (specified in the deployment file).
Restore the snapshot created in Step #2 (voltadmin restore).
Return the database to normal operations (voltadmin resume).
