How to upgrade Opencart Extension?

Let's say we want to upgrade the X-Shippingpro module. Here are the steps you have to follow to upgrade it.

If your extension installer is functional (it means you are able to install any module through using it), upgrade progress is straightforward.

1. Go to extension installer, now choose the updated xshippingpro.ocmod.zip for your OC version.

2. Now go to the Modification list, click the `Refresh` button to refresh the ocmod list

3. Now navigate to the module and click the `Save` or `Save and Stay` button to sync with all new changes. Please take note if the module has multiple tabs, you have to click each tab to load its corresponding content and check if everything is correct. Sometimes you might need to adjust the settings for the new options. Finally, click the `Save` or `Save and Stay` button to sync with all new changes.

If your installer is not functional, you can upload files using FTP

1. Unzip the xshippingpro.ocmod.zip, and you will get a directory called `upload`

2. Now upload all files and folders from the `upload` directory on your server with preserving the opencart directory structures.

3. Now go to the Modification list, click the `Refresh` button to refresh the ocmod list

4. Now navigate to the module and click the `Save` or `Save and Stay` button to sync with all new changes. Please take note if the module has multiple tabs, you have to click each tab to load its corresponding content and check if everything is correct. Sometimes you might need to adjust the settings for the new options. Finally, click the click the `Save` or `Save and Stay` button to sync with all new changes.

(Warning DON"T UNINSTALL current version, if you did that, all existing data would be lost)
