Field type change without effecting data in that field

[Maximus]

Hello.
There is no such possibility in the UI to change the field type while the field is already created. The field type can be set only when the new field is creating.
Of course, you can try to redefine the field type in the code, but I am not sure that this is safe.

Hi,

How to change field type without effecting data in that field.

Eg -
Field Name - Invoice No
Field Type - Float

So I want to change Float to Int without effecting existing data in that field.

Can anyone let me know how to do it if its possible.
