Hi Marvin,
Thank you for posting your concern.
Please note that according to this
document, metrics will be reset after migration to assets. The legacy metrics will be available for a short period of time after migration, but will be removed at some point in future.
Also, if you want to get the metrics of the extension migrated to asset-based, then I would suggest using the following report types depending on what level you want to get this information:
ad_group_asset
asset_field_type_view
campaign_asset
customer_asset
