docs/src/developer/reference/config-options.md:1885

• The documentation should be updated to include the team features migration metric name. After line 1885 where conversation codes metric is mentioned, you should add information about the team features migration metric: wire_team_features_migration_finished.

   Wait for the store-specific migration metrics to reach `1.0`. For
   conversations: `wire_local_convs_migration_finished` and
   `wire_user_remote_convs_migration_finished`. For conversation codes:
   `wire_conv_codes_migration_finished`.
