If a time series was created before in Apache IoTDB, and the data type was FLOAT. Also, part of the data has already been inserted in the time series. Now I want to change the data type of time series to DOUBLE. I wonder if IoTDB can change the data type of time series? If it can, how can I do this?

I stop the server to prevent any further data insertion or query execution. Then, I use the ALTER statement to modify the data type of the time series.

You can create another time series in Apache IoTDB with DOUBLE datatype, and use select into to write the original data into this time series.
