Upgrading an add-on
To upgrade an add-on, navigate to Marketplace and click on the add-on you want to upgrade. Note that in the Marketplace, you can only upgrade add-ons for user or groups. Upgrading add-ons for all users in the system should be handled by the system administrator via the System Marketplace
On the add-on's details page, click Upgrade to install the latest version of the add-on.
The upgraded version of the add-on will be installed at the same scope as the version currently installed on the account (Note: add-ons can be installed on different levels, including system, organisation, group or user) Confirm the installation by clicking Upgrade in the pop-up window.
The upgraded add-on will automatically appear under the Installed add-ons tab in the Marketplace.
