1644846 - Migrate Firefox iOS legacy telemetry metrics to Glean

Status: RESOLVED FIXED

(Data Platform and Tools :: Glean: SDK, task, P1)

Description

[Travis Long [:travis_]]

This bug tracks the telemetry team's work to aid in migrating legacy Firefox for iOS metrics to Glean. The initial integration has already been completed, so this leaves the remaining steps from the Glean migration checklist:

• Validation of the initial integration
• The metrics migration worksheet
• Migrate legacy telemetry-ios metrics to Glean. (this bug)
• Verify that data for the new/ported over metrics is flowing in
• Remove legacy telemetry-ios.

Marissa was so kind as to share this doc which covers some of the questions that Fx-iOS product team seeks to answer.

Marissa is also working to make our metrics more consistent across products (such as Fenix), so her input on the metrics migration process will be important.
