To upgrade an existing Google Tag Manager (GTM) account to Universal Analytics, you need to follow these steps:

1. Login to your Google Tag Manager account.
2. Click on the "Admin" button on the top navigation bar.
3. In the "Properties" column, select the property that you want to upgrade to Universal Analytics.
4. Click on the "Tracking Info" option.
5. Select "Tracking Code" from the dropdown menu.
6. Click on the "Universal Analytics" option.
7. Follow the instructions on the screen to complete the upgrade process.

Once you have completed the upgrade process, you will need to update your tracking code on your website with the new Universal Analytics tracking code. You can also use Google Tag Manager to deploy the Universal Analytics tracking code on your website.

Note: Make sure to test the new tracking code to ensure that it is tracking the correct data before deploying it to your live website.
