Updating an encapsulated plugin

Updating the version of an encapsulated plugin on your store

This help file describes newer “encapsulated” plugins that are installed under zc_plugins. For older plugines which are copied directly into the includes and admin folders, see How to install a non-encapsulated plugin.

This guide is about updating plugins which are already installed. For basic plugin information and a how-to on installing plugins, see How to install an encapsulated plugin.

Getting Started

Before you start, you’ll need to verify that you have some things.

  • Plugins are provided in zip format, so you’ll need a tool to unzip the file.
  • You’ll need a tool to transfer the files from your local PC to your webserver.

Updating

  • Copy the files from the unzipped plugin into the zc_plugins folder in your cart. You will now see multiple folders under the plugin’s name folder. For example, with POSM, under zc_plugins/POSM/ you might see folders for v6.1.1 and v6.2.0.

  • In your admin, navigate to Modules > Plugin Manager.

  • Select the new plugin you wish to update.

  • You will see in the right hand infobox that the “Upgrade Available” button is shown. Click it.

Encapsulated Upgrade Step 1

  • Select the version and click “Upgrade” again.

Encapsulated Upgrade Step 2

  • A dialog is persented which allows you to cancel. Instead, click “Upgrade”

Encapsulated Upgrade Step 3

  • Once this is complete, the infobox will show the plugin running the upgraded version. You’re done!

Encapsulated Upgrade Step 4
