This tutorial is based on the premise that you have the licenses for all the components on your site loaded into the respective component configuration.
Specifically we will focus on Ready Labs-Entension Manager and the default Joomla extension updater.
On the control panel of your site you will see a red banner stating updates are needed
Got to COMPONENTS>>READY LABS: EXTENSION MANAGER
If updates are needed there will be yellow buttons. Select the UPDATE ALL button at the top.
Go to EXTENSIONS>>MANAGE>>UPDATES
If the updates are successful a green message bar will appear with the details of the successful updates.
