Efficient Data Migration from Universal Analytics to BigQuery

The sunsetting of Universal Analytics (UA) on July 1, 2024, will permanently alter how businesses access and utilise historical data.

Why You Should Care About Saving Universal Analytics Data

Universal Analytics (UA) has been a cornerstone for marketers, analysts, and business owners seeking to understand customer behaviour and improve digital marketing strategies. The detailed reports and insights generated by UA have informed countless business decisions. However, starting July 1, 2024, it will cease to exist, and with it, access to historical data through its interface and API will be lost forever.

The loss of historical data means losing the ability to:

  • Compare past and present performance, crucial for understanding trends and growth.
  • Analyse long-term data for better strategic decisions.
  • Benchmark new metrics against old data, vital for measuring the impact of any changes or optimisations.

How to Preserve Your Universal Analytics Data

This blog post explores a practical solution: backfilling Universal Analytics data into BigQuery. We’ll discuss why this is essential, the benefits it offers, and provide a step-by-step guide to executing the backfill successfully.

Why Backfill Universal Analytics Data into BigQuery?

Backfilling this data into BigQuery offers several advantages:

  • Data Continuity: Ensures uninterrupted access to historical data for comparison and analysis alongside new GA4 data.
  • Advanced Analytics: Leverages BigQuery’s powerful data warehousing capabilities to perform more complex queries and analyses than possible in UA.
  • Integration Opportunities: Facilitates integration with other data sources in BigQuery, providing a more holistic view of business metrics.

Step-by-Step Guide to Backfilling UA Data into BigQuery

1. Export Data from Universal Analytics

The first step involves exporting your historical UA data. You can do this through the Google Analytics Admin interface or by using the Google Analytics API. Export the data in a format compatible with BigQuery, such as CSV or JSON.

2. Prepare the Data for Import

Once you have your data, it may require some cleanup and transformation to match the schema used in BigQuery. Tools like Google Cloud DataPrep can be used to transform data formats, handle missing values, and ensure data types are consistent.

3. Create a BigQuery Dataset

Before importing your data, you need to create a new dataset in BigQuery. This is where your UA data will reside. Define a schema that closely matches the structure of your UA data to facilitate easier querying and analysis.

4. Import Data into BigQuery

With your dataset ready, import your prepared UA data into BigQuery. This can be done through the BigQuery UI, command-line tools, or Google Cloud APIs. Ensure that the data loads correctly and validate its integrity.

5. Query and Analyse

Now that your data is in BigQuery, you can begin querying it alongside your GA4 data. Use SQL queries to perform comparative analysis, generate reports, and derive insights that were previously conducted in Universal Analytics.

Benefits of Having UA Data in BigQuery

Integrating UA data into BigQuery not only safeguards your historical data but also enhances your analytics capabilities:

  • Scalability: BigQuery’s infrastructure supports massive datasets and complex queries without performance degradation.
  • Cost-Effectiveness: With its pay-as-you-go model, BigQuery can be more cost-effective than maintaining legacy analytics systems.
  • Real-Time Insights: Combine real-time data processing with historical analysis to gain more immediate and actionable insights.

Backfilling Universal Analytics data into BigQuery is a strategic move to preserve valuable historical data while leveraging advanced analytics capabilities. By following the steps outlined above, businesses can ensure they continue to derive valuable insights from their past data, aiding in smoother transitions and informed decision-making.

This transition not only safeguards historical insights but also sets the stage for more advanced data exploration and utilisation, making it a worthwhile endeavour for any data-driven organisation.

Act now to safeguard your data and maintain your competitive edge. Secure your Universal Analytics data by backfilling it into BigQuery today!
