### Description

We have a collection containing data with properties. We want to remove some of the properties from the schema if possible. We also want to change the data type of an existing property from `text` to `text[]`. It would be ok to lose existing data of type `text` for this property. Am I correct in the assumption that this is only possible by creating a new collection and migrating the data? Or would there be an easier way to achieve this?

Hi @torbenw !!

You are correct! You will need to migrate your data over to a new collection that has the schema you want.
