JCK Manager: Upgrading - Automatic update process
The good news is that the core ‘JCK 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 a 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).
Next do this go to ‘Extensions’ > ‘Extension Manager’ > 'Update'. Next click on the ‘Find Updates’ icon (top right corner). Next ‘Select’ the update package and click the ‘Update’ button.
Depending of speed of your server and connection bandwidth, this process can take from few minutes. So, please be patient and don't interrupt the update process.
