[UA→GA4] Automatically created Google Analytics 4 properties

We strongly recommend you manually migrate your Universal Analytics settings to GA4. If you do nothing, a new GA4 property will automatically be created for you, and your Universal Analytics configurations will be copied to the new GA4 property. Not all UA configurations have an obvious GA4 counterpart, and the automated process might not make the same choices as you would.

Google Analytics 4 is replacing Universal Analytics. On July 1, 2023, your Universal Analytics properties will stop collecting data. Only GA4 properties will collect data after July 1. To help you with this transition, beginning in March 2023,

• We'll create a GA4 property for you, based on the settings in your Universal Analytics property, unless you opt out.
• If you have already created a GA4 property, and that property is connected to a Universal Analytics property, we'll copy over any configurations (e.g., goals, audiences, etc.) from your Universal Analytics property that you have not marked as complete in your GA4 property, unless you opt out.

Note to Google Analytics 360 customers: This article applies to any standard (i.e., non-360) properties you may have under your 360 account. You must opt out any standard UA properties that you don't want recreated as GA4 properties.

How to opt out

If you opt out, a new GA4 property will not be created for you. If you have already created a GA4 property, no configurations will be copied over from the connected Universal Analytics property, regardless of whether they have been marked as complete or not.

To opt out, you need the Editor role on your Universal Analytics property.

1. In Google Analytics, click Admin.
2. Make sure you are in the correct account and Universal Analytics property.
3. In the Property column, click GA4 Setup Assistant.
4. At the bottom of the page, turn off the Automatically set up a basic Google Analytics 4 property toggle.

Alternatively, click Manage GA4 migration in the yellow informational banner at the top of your Analytics account. Turn off the Automatically set up a basic Google Analytics 4 property toggle.

You can also opt out using the Google Analytics Admin API.

If you didn't opt out in time

If you didn't opt out in time and don't want your automatically configured Google Analytics 4 property:

1. Click Admin.
2. Select your Universal Analytics property.
3. In the Property column, click GA4 Setup Assistant.
4. Next to "Connected property", click Disconnect.
5. Go to your GA4 property and delete it.

If you've already created a Google Analytics 4 property

If you want us to copy over some, but not all Universal Analytics configurations to your GA4 property:

1. Click Admin.
2. Select your GA4 property.
3. In the Property column, click Setup Assistant.
4. Mark the configurations that you don't want copied over as complete.
   1. Click the arrow at far right.
      
   2. Select Mark as complete.
      
5. Repeat this step for each configuration that you don't want copied over from Universal Analytics. (In this case, the progress bar will show "8 of 12 marked complete".)
   

To ensure that your configurations are copied over from the correct Universal Analytics property:

1. In your Universal Analytics property, go to Admin > Property > GA4 Setup Assistant.
2. In the I want to connect to an existing Google Analytics 4 property section, select the Google Analytics 4 property that maps to your Universal Analytics property.
3. Click Connect properties.

See your new Google Analytics 4 property

After your Google Analytics 4 property has been automatically created, you'll see a blue informational banner at the top of your Analytics account. Click Open Setup Assistant to go to the Admin section of your new Google Analytics 4 property. The Setup Assistant in your Google Analytics 4 property guides you through additional features and settings that you might want to set up. Learn more

In the top-left corner of the Analytics interface is a menu you can use to switch between all of the Analytics accounts and properties for which you have permission. Learn more

How it works

Automatically created Google Analytics 4 properties can help you start your migration from Universal Analytics. Expand each of the following sections to see more details about your automatically created Google Analytics 4 property.

You can also visit change history in your Google Analytics 4 property to see a record of some automatic changes to your property.

Create a GA4 property and web data stream

Your automatically created Google Analytics 4 property will have the same industry category, reporting time zone, and currency as your Universal Analytics property's default view.

It will also have the same property name but with "- GA4" appended to the end of it. For example, if your Universal Analytics property name is "Example property (UA-nnnnnnn)", your GA4 property name will be "Example property - GA4 (xxxxxxx)", without a "UA-" prefix, and where xxxxxxx is a new property number.

Your new GA4 property will also have a new web data stream configured. If you're trying to measure an app, you'll need to create an app data stream and configure your app to send data to GA4.

Copy UA property-level users

Your new Google Analytics 4 property will have the same Universal Analytics property-level users with equivalent permissions. View-level users won't be copied.

Reuse an existing site tag, when possible

If your website is tagged with the Google Tag (gtag.js), your automatically created Google Analytics 4 property will use a connected site tag to receive data. Connected site tags do not affect data collection for your Universal Analytics property.

If your website has an analytics.js tag, including through a tag management system like Google Tag Manager, your automatically created Google Analytics 4 property will also receive data via a connected site tag. Many content management systems (CMSs) will have already deployed a Google Tag for you; if not, we will create a connected site tag for you.

Not every customer will be eligible for site tag reuse. If not, they'll need to manually add the Google tag or configure Google Tag Manager for their Google Analytics 4 property to receive data. For example, you will need to retag your site if you use ga.js, urchin.js, or advanced analytics.js features including: using Tasks, changing any default cookie configuration or behavior, changing client id, overriding any of the document (page) parameters or the referral source, disabling advertising features, or changes to property processing rate.

Reproduce UA events using the GA4 data model

There are differences between the Universal Analytics and Google Analytics 4 data models, so your Google Analytics 4 data will look different from your Universal Analytics data. 

If you have any custom events set up in your Universal Analytics property, your new GA4 property will automatically collect them as GA4 custom events. The category/action/label values from your UA events automatically get translated to Google Analytics 4 events and parameters as follows:

• Event action becomes an event name in the Google Analytics 4 property.
• Event category, label, and value become event parameters in the Google Analytics 4 property.

This allows your Google Analytics 4 property to collect information that's not collected by default. To display this information in reports, "event_category" and "event_label" event-scoped custom dimensions will also be automatically created. 

Reproduce UA event and destination goals as GA4 conversions

Universal Analytics properties can have several different goal types. The following goal types can be automatically migrated:

• Destination: When a user lands on a specific page, such as a "thank you" or "confirmation" page
• Event: When a user triggers a specific event, such as social recommendation, video play, or ad click

Smart goals aren't eligible for automatic migration.

Your automatically created Google Analytics 4 property will have event creation rules and conversion events that imitate each eligible Universal Analytics goal. Goals are copied from your Universal Analytics property's default view, and from any other views that have goals used in Google Ads.

Reproduce UA audiences in GA4

Many of your UA audiences can be automatically migrated. Audiences are copied from your Universal Analytics property's default view, and from any other views that have audiences used in Google Ads. 

Migrate Google Ads links from UA

All eligible Google Ads links from your Universal Analytics property will be copied to your Google Analytics 4 property, and you'll begin seeing Google Ads data in your Google Analytics 4 reports.

Data from your Google Analytics 4 property will also be available to linked Google Ads accounts. 

Swap UA conversions used in Google Ads with GA4 equivalents

If you import conversions from your Universal Analytics property into Google Ads and use them for bidding, these goals will be switched to the GA4 equivalent. This involves the following steps in your Google Ads account:

• import the equivalent GA4 conversion event
• set its action optimization setting to primary
• set the Universal Analytics conversion's action optimization setting to secondary. 

If you use a Universal Analytics conversion in a Google Ads custom goal, then the Universal Analytics conversion will be removed and replaced with an equivalent GA4 conversion.

If you use a Smart Campaign, your conversions will be calculated with the Ads-preferred last click attribution model in Google Analytics before being imported into Google Ads. This helps capture more conversions.

Pair UA audiences used in Google Ads with GA4 equivalents

If you import audiences from your Universal Analytics property into Google Ads and apply them to advertising campaigns, these audiences will be paired with the GA4 equivalent whenever possible.

Next steps

Automatically created Google Analytics 4 properties contain only basic features. Depending on your business and measurement needs, you might want to set up additional features to get the most value out of your new property.

You can also compare key metrics from your Universal Analytics property to those in your new Google Analytics 4 property, and take steps to align configuration and bring the metric counts as close as possible.

If you're an advertiser, you can similarly compare imported Universal Analytics and Google Analytics 4 data in Google Ads.
