Upgrading - Automatic Update Process
The good news is that the core 'Ark Editor' and 'Component' utilises Joomla’s Update Manager so the whole upgrade process is automated and very simple.
Before starting, it is advisable to create and restore points prior to upgrading. This can be done by exporting a backup of your custom configuration as a tar.gz (please see: Backup and Restore for instructions on how to do this).
To do this go to 'Extensions' > 'Extension Manager' > 'Update'. Click on the 'Find Updates' icon (top right corner). Next select the update package and click the 'Update' button.

Depending on the speed of your server and connection bandwidth, this process can take a few minutes. So please be patient and don't interrupt the update process.
