I think instead of copy past table export-import  data will be way easy 

create a new model using py with the same field and type ( without x_ prefix)
Export CSV file from an existing model created using GUI
Import CSV file to new model create by .py

Hi, thanks for the response, is there not a more smart way to do it? If I define the model from code, can I switch the table is such a way?

Hi,

I will suggest you to do add new model from the code and copy the existing data in the current model to the new table. During the copy to new table, try to keep same id for the records.

Thanks
