I am working on upgrading the Google Analytics to Universal Analytics, In the guidelines, it is mentioned that, it takes nearly 24-48 hours to complete the upgrading process. I need to know whether it is possible to track GA event when transforming from Google Analytics to Universal Analytics process is going on?
Your events will continue to tracking using ga.js while the property is migrating.
The documentation under Universal Analytics Upgrade Center - Upgrade Guide (Important Considerations) states:
"...data sent via a legacy library or protocol to a property that has been transferred to Universal Analytics will continue to be processed and appear in your reports until it is deprecated in Phase 4 of the Universal Analytics Upgrade."
And from the Upgrade to Universal Analytics documentation within GA:
To ensure you continue to collect high quality data, don’t make any changes to your tracking code until the transfer is complete.
