People who still use the Hangouts mobile app will see a prompt to move to Chat.
The Google Hangouts web app is no longer available.
This was the last Hangouts offering available to users. The Android and iOS apps died in July of this year.
While most of the messages and contacts will be automatically transferred over, all of the data won’t migrate to Google Chat. The company notes that users should use Google Takeout to download and save a copy of their data. Users have until January 2023 to keep their Hangouts data.
