Is it possible to change the type of a property?

At present, it is not possible to change the type of a property in your data model, as this could lead to a break in your data history.

You can always deactivate your old property by changing its status, and create a new one with the correct type.

Note that disabling a property will not allow you to reuse its property key, which is the unique key that differentiates it from other properties.
