How long does it take to migrate from UA to GA4?

The process can take anywhere from a few days to a few months, depending on the complexity of your website or app and your team’s skills. Moving to the new Google platform includes some standard steps, such as setting up new properties, implementing new tracking codes, configuring streams and events, and setting up reports. But in most cases, a successful transition will also require extensive product training for your team. You need to ensure they are not intimidated by the complexity of the new platform and feel confident using new reports and metrics to evaluate the performance of their work. So if you plan to switch to GA4 before July 2023, you should start immediately.

Can I migrate historical data from UA to GA4?

No, you can't. Since you won't be able to keep your data anyway, the sunset of Universal Analytics creates an excellent opportunity for companies who'd like to replace GA with a different tool. GA4 is known for its complexity and steep learning curve, so choosing a platform based on concepts you're already familiar with might ease and speed up your onboarding process.

How long does it take to migrate from Universal Analytics to Piwik PRO?

It’s easy to transition between Google Analytics and Piwik PRO because of similar UIs, data layer compatibility, detailed onboarding materials (Core plan), and dedicated support (Enterprise plan). Core plan users will be able to migrate their analytics setup within an hour. With the Enterprise plan, you’ll get extra services related to product implementation and training. In this case, onboarding takes around four weeks, depending on the complexity of your tracking setup.

What makes Piwik PRO a great alternative for people unhappy with losing Universal Analytics?

There are several factors that make Piwik PRO a perfect successor for the sunsetting UA:
  • Painless migration – the similarities between platforms mean you’ll be able to move your analytics setup and start collecting data in less than an hour.
  • No need to learn new concepts from scratch – feel at home with reports and metrics based on similar methodology to UA.
  • More flexibility in using data – get access to advanced reports that support all event-based use cases, retrieve raw data, and push it to data warehouses, BI tools, data visualization platforms, and other parts of your tech stack.
  • Improved data accuracy – use software that can run without consent and complies with the guidelines of data protection authorities across Europe.
  • Privacy compliance – collect data in line with GDPR, HIPAA, CCPA, TTDSG, and other privacy laws worldwide. Make compliance easier with an integrated consent manager.
