Every change to a guardrail creates a new immutable version in Agent Platform. Browse the version history to review previous versions and restore any of them. [Restore a version directly](docId\:Bn2f1jbR-4aajrNIQJIHZ) from the list, or [preview the version in read-only format](docId\:Bn2f1jbR-4aajrNIQJIHZ) first.

Restoring creates a new version that copies the selected version. The copy includes the rule text, block message, training data, and trained model. Restoring does not modify or delete the original version. When the restored version includes a trained model, the new version is available for activation without retraining.

## Open the version history

To view the version history of a guardrail, complete the following steps in Mark:

1. Go to **Agents > Input Guardrails**.
