Help needed for merging two values in influxdb

Due to renaming I would like to merge old-entity to new entity in influxdb. I am trying to do this this way according description in german Influxdb umbenennen von Measurements

select * into db_name..new_entity from db_name..old_entity
drop db_name..old_entity

My query in Influx db executes without error but also without effect:

select * into home_assistant..temperature_humidity_outdoor_temperature from home_assistant..wohnzimmer_wohnzimmer_wohnzimmer_vorgarten_temperature

Query of “old value” return no results.

select * from home_assistant..wohnzimmer_wohnzimmer_wohnzimmer_vorgarten_temperature

However I can see old and new value in grafana without problems.
Please help me in correcting the query in order to to the intended copy of all values from old.
