====Upgrading ARDI - Linux====

On Debian-based systems, the user will need to login via a terminal/SSH in order to begin the upgrade process.

An ARDI upgrade on a Linux system is effectively just an in-place re-installation. 

<code>
cd /usr/src
wget http://repo.optrix.com.au/linux/installer
chmod u+x installer
./installer
</code>

This will upgrade all of the packages on your system, ensure that all prerequisites are properly installed, and will replace all of your ARDI installation files with new versions.

===Checking the Results===

After the automated upgrade is complete, you should visit **every** [[ARDI database|ARDI database]]  to ensure that any updates are applied and all are still working as expected.

New features sometimes require changes to the database or cache structure. These changes are applied the first time someone visits the web-interface for each database. This means that verifying that each database is working is actually a //vital// part of the update process.
