Can you please fill out a data review request? :) https://github.com/mozilla/data-review/blob/master/request.md

[ValentinTimisica]

Request for data collection review form

All questions are mandatory. You must receive review from a data steward peer on your responses to these questions before shipping new data collection.

1. What questions will you answer with this data?

• If the current app is Fenix.
• If the migration from Fennec to Fenix completed successfully.

2. Why does Mozilla need to answer these questions? Are there benefits for users? Do we need this information to address product or business requirements?

• Leanplum marketing campaigns.

3. What alternative methods did you consider to answer these questions? Why were they not sufficient?

• N/A

4. Can current instrumentation answer these questions?

• No.

5. List all proposed measurements and indicate the category of data collection for each measurement, using the Firefox data collection categories on the found on the Mozilla wiki.

• Category 1.

6. How long will this data be collected?

• N/A

7. What populations will you measure?

• All release, beta, and nightly users with telemetry enabled.

8. Please provide a general description of how you will analyze this data.

• Leanplum

9. Where do you intend to share the results of your analysis?

• Only on Leanplum with the people who have the right permissions.

As @lwa-moz suggested in this comment I also added a E_Fennec_To_Fenix_Migrated Leanplum event which will be sent when the user has successfully migrated from Fennec to Fenix.

Added @jonalmeida and @pocmo as reviewers

[pocmo]

This should work. As an alternative we could also emit a Fact from the component. With that you wouldn't need to listen here indefinitely.

[boek]

@pocmo if that is easy let's do it. I'm going to land this for now. I filed mozilla-mobile/android-components#5929, if that lands I'll factor out this code and use the Fact instead 👍

[jonalmeida]

I've put up a PR for this: mozilla-mobile/android-components#5932

[st3fan]

@ValentinTimisica @boek if we want this to land in the last Migration Nightly build (which we will do tomorrow) then this needs a data review and land today.
