# Upgrading from Deprecated Google Tag Manager Extension to GA4

## Problem

You have an existing WeltPixel Google Tag Manager (GTM) extension and want to purchase a support & updates renewal period for your license. However, the legacy Google Tag Manager extension has been deprecated and is no longer available for support renewal.

## Solution

The legacy Google Tag Manager extension is no longer maintained. To continue receiving updates and support for Google Analytics tracking, you need to migrate to the **Google Analytics 4 (GA4) with GTM Support** extension.

### Migration Steps

1. **Purchase the GA4 extension** - This is a separate product that replaces the deprecated GTM extension

2. **Remove the legacy GTM extension** manually. This extension predates Composer installation, so it needs to be removed from the file system. Delete the module directory from **app/code/WeltPixel/** (the GoogleTagManager module folder), then run the standard cleanup commands:
```bash
   php bin/magento setup:upgrade
   php bin/magento setup:di:compile
   php bin/magento setup:static-content:deploy
   php bin/magento cache:flush
```

3. **Install the GA4 extension** following the standard installation process provided with your purchase

4. **Reconfigure your tracking settings** in the Magento admin panel under the new GA4 extension configuration

## Why This Change?

Google has transitioned from Universal Analytics to Google Analytics 4 as its primary analytics platform. The GA4 extension provides:

* Full GA4 event tracking support
* Google Tag Manager integration
* Enhanced ecommerce tracking for GA4
* Ongoing updates and compatibility with future Magento versions

## Verification

After installation and configuration:

1. Navigate to **Stores > Configuration > WeltPixel > Google Analytics 4** in your Magento admin
2. Verify your GA4 Measurement ID is configured correctly
3. Test tracking events using Google Tag Assistant or your GA4 real-time reports
4. Confirm ecommerce events are firing correctly on product pages and checkout
