Edit data type for an existing custom property

Good day everyone,

Simple question, as in the title, is it possible to edit the data type of a custom property (i.e. previously created as varchar, to be made as int.) via SQL ?

I mean, I know that SQL will allow me to do that, but I don't know if Orion will like it.

Same question applies also to the name of the column.. is it possible to change it?

Thanks.
