Event Schema Edit Breaks Data View Configuration

[tenthe]

Body

Issue Description

In the Data Explorer, when the event schema is edited (e.g., in a pipeline or an adapter), the widget configuration may break because the event schema is not updated.

Steps to Reproduce

1. Create a machine data simulator with the "persist" option enabled.
2. Create a data view.
3. Edit the event schema of the adapter (e.g., rename a property).
4. Choose the option to migrate pipelines.
5. Return to the data view.

Expected Behavior: The event schema in the data view should match the updated schema.
Actual Behavior: The event schema options in the data view may differ from the actual schema.

Resolution Requirements

Before resolving this bug, it's crucial to determine how to address this issue, particularly in handling old data and the outdated schema.

Hi @tenthe, thanks for reporting this.
Since this involves handling old data and schema migration, is there an agreed approach already, or should this be discussed before implementation?
