Changing the schema of a card
The schema of a card can be changed. Optionally, you can change the schema of all the cards in that map and in referenced maps that use the previous schema. When the schema for a card is changed, you can choose to replace all references to that schema with the new schema.
In some situations, you would not want to replace all references to the schema. For example, if only the input of the selected schema had changed, you would not want the output to change.
