- This data migration intends to convert the worldmap widgets to table
widgets with the following changes:
- - Display type of Widget is changed from 5 (world map) to 4 (table).
- - `'has:geo_country_code'` condition is addded to each Widget Query.
- - Added `'geo.country_code' `and `'geo.region' `columns to each Widget
Query.
- - Added `'geo.country_code'` and `'geo.region'` fields to each Widget
Query.
- - Aggregates and order columns remain unchanged.
