Since the release of the latest version 4, Google has been giving its users options to choose whether to work with it or use the previous version they are used to – Universal Analytics. However, on March 16 of this year an official announcement was published that the Universal Analytics service will be retired effective July 1, 2023.
With the final discontinuation of Universal Analytics, users should be aware that if they do not switch to Google Analytics 4, this will not happen automatically in the middle of next year. Each user must make the change manually to save their work and collected website history for the future.
After 1.06.2023, Universal Analytics will stop processing data for new visits, and within at least 6 months there will be an option to transfer the saved history to Analytics 4. It is to be further announced by which date this option will be possible.
