How to Move Container Information from One GTM Container to Another

Step 1: Open the Source Container (The One You Want to Copy From)

1. Go to https://tagmanager.google.com
2. Sign in with your Google account
3. Select the GTM account and container that has the setup you want to move
4. In the left menu, click Admin

Step 2: Export the Container

1. In the Admin section, find the Container column
2. Click Export Container
3. Choose the Container Version you want to export:
4. Select the Latest version or another version from the dropdown
5. Click Export
6. A JSON file will be downloaded to your computer. (This file contains all the Tags, Triggers, and Variables from the container)
7. Rename the JSON file to something easy to recognize like GTM-MyWebsite-Export.json

Step 3: Open the Destination Container (The One You Want to Copy To)

1. Go back to https://tagmanager.google.com
2. Choose the GTM account and container where you want to import the information
3. Click Admin in the left-hand menu

Step 4: Import the Container

1. In the Admin panel, under the Container column, click Import Container
2. Click Choose container file and select the JSON file you exported earlier

Step 5: Choose Import Options

You’ll be asked how to handle the import:

Two Options:

Option	What it does
Overwrite	Deletes all current tags/triggers/variables in the destination container and replaces them with the imported ones
Merge	Adds the imported tags/triggers/variables without deleting the existing ones

*Use Merge to keep the existing setup and avoid accidental data loss.

Step 6: Preview and Confirm

1. GTM will show a list of what will be imported
2. Review the changes carefully
3. Click Confirm

Step 7: Save and Publish

1. After importing, go to Workspace
2. Use Preview Mode to test that everything works correctly
