As the title says. Is there a way to update a property of a class schema? I know we can add a new property, but not sure about modifying an existing one. I have a cross-reference field that currently accepts 2 types of data, and want to add a third one.  
Thanks.

Hi!

I believe this is currently not possible. According to this doc:

> **[Schema | Weaviate - vector database](https://weaviate.io/developers/weaviate/configuration/schema-configuration#add-a-property)**
>
> Overview

It states that properties cannot be renamed or deleted once it was added.

You can add new properties, and even change some of their parameters, even though many parameters are immutable and cannot be changed once set.

Let me know if this helps!

Thanks!
