How to Alter the tag and field keys of a measurement

Hi,I have a measurement which has one tag value and one field value.

insert abc,temp=20 dept=12
select * from abc
name: abc
time dept temp

1613553100294732034 12 20

show tag keys from abc
name: abc


show field keys from abc
name: abc
fieldKey fieldType

dept float

Now i want to swap the filed as tag and tag as field, is it possible to do in same measurement,if not how can we?
