Policy revision supports the revert policy function 7.4.2

This information is also available in the FortiManager 7.4 Administration Guide: Reverting a Policy to a previous version

When a policy is created or edited, the history of the change is saved as a revision. You can view a policy's revisions in the Revision History table when editing the policy.

FortiManager policy revisions support the revert policy function. The example below demonstrates how you can revert a policy to a previous version.

To revert a policy to a previous version:

1. Create a new policy.
   In this example, a firewall policy is created with the action set to Deny.
   

2. Edit the policy, and save the changes.
   The Action is changed to Accept, and the Service to GTP.
   

3. Edit the policy again, and review the Revision History log. You can see that revisions were added when the policy was created and edited.
   

4. Select a revision, click Revert, and click OK.
   
   The policy is reverted to the previous state. In this example, the policy is reverted to use the Deny action and the GTP service is removed.
   
   A new revision is added to the table to log the change with the note "Reverted to revision #".
