The process of installation is pretty simple; see the Quick Start Guide for details.
But how do we easily upgrade between versions? The key is judicious use of STARDOG_HOME . Best practice is to keep installation directories for different versions separate and use a STARDOG_HOME in another location for storing databases.[3] Once you set your STARDOG_HOME environment variable to point to this directory, you can simply stop the old version and start the new version without copying or moving any files. You can also specify the home directory using the --home argument when starting the server.
Shall it rather say "stop the old version unzip the new version , then start the new version"?
