How can you change the Entity identifier to auto-increment?

The option that allows you to change the Entity identifier to auto-increment effectively involves copying the current Entity, deleting the original, and pasting it back with modifications to the identifier properties. This method allows you to retain the settings and relationships associated with the Entity while making the necessary adjustments to the identifier.

When you copy and paste the Entity, you can then set the identifier to auto-increment in the new version, ensuring that it is correctly configured for that functionality. This process helps in maintaining the integrity of the database while adapting to the new identifier requirements.

Changing the Id directly in the Entity properties is not an option because, in many development environments, such properties may not support direct modification especially if auto-increment functionality is not enabled by default. Creating a new Entity each time would be impractical and inefficient, as it would lead to redundancy and potential data loss. Similarly, using a specific command in the OutSystems IDE might not be a standard method available for changing an Entity's properties, especially in a way that allows for this specific update to auto-increment.

By following the method described in the correct choice, developers can ensure a seamless transition to using an auto-increment identifier while minimizing disruptions to the application’s architecture.
