Installation, Configuration, Upgrade and Migration

The DBA should have knowledge of the hardware and software requirements for running the database server efficiently.
The DBA should later communicate these requirements to the system administrator and install the database and various options in the database product for deploying the database.
The DBA should install the latest releases and patches and keep the database up-to-date, robust and efficient.
The DBA should migrate the database from the old database server to the new one in case a new server is installed to increase the database's speed and efficiency.
