Specifically, there have been significant changes in how certain chart types are handled, such as the migration of `dist_bar` to `echarts_timeseries_bar` and `bubble` to `bubble_v2`, which involve renaming keys, removing certain keys, and setting default values <sup>[[1]](https://github.com/apache/superset/blob/master/superset/migrations/shared/migrate_viz/processors.py)</sup>. To address this issue, you might need to: 1. **Check Chart Configurations:** Review the configurations of your charts to ensure they align with the new data model. Pay attention to any renamed or removed keys and update them accordingly. 2. **Migration Scripts:** Although I couldn't find specific migration scripts or tools in the repository, it's worth checking if there are any available in the Superset documentation or community resources that could assist with the transition. 3. **Manual Adjustments:** If automatic migration tools are not available, you may need to manually adjust the chart configurations to match the new version's requirements. Recreating all charts from scratch might not be necessary if you can adjust the existing configurations to fit the new model. However, if the changes are extensive and manual adjustments are not feasible, recreating the charts could be a more straightforward solution. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
