Google Analytics 4 (GA4) Migration Guide

Upgrading to 2.0.0​

A major update of most streams to avoid having duplicate stream names. This is relevant for the connections having more than one property ID. Resetting a connector is needed if you have more than one property ID in your config.

Let's say you have three property IDs - 0001, 0002, 0003. Two of them will be included in the stream names:

  • "daily_active_users",
  • "daily_active_users_property_0002",
  • "daily_active_users_property_0003",
  • "weekly_active_users",
  • "weekly_active_users_property_0002"
  • "weekly_active_users_property_0003" ...

If the number of properties in your config does not exceed one, you will not see changes to your stream names, and the reset is not required:

  • "daily_active_users",
  • "weekly_active_users"

Once you add the second property ID, new streams will have names with the new property ID included. Existing streams will not be affected:

  • "daily_active_users",
  • "daily_active_users_property_0002",
  • "weekly_active_users",
  • "weekly_active_users_property_0002"

If you add the second+ property after running the upgrade, the reset is not required.
