Create a new version of the policy, make the necessary changes to the new version and switch the new version to the Productive state when you are ready to put it into effect. Switching the new version to the Productive state will immediately put the previous version in the Retired state. (The Retired state is an end state. After you place a policy in this state, you can no longer reactivate it.)

Create a completely new policy that includes the required changes. When you are ready to put the new policy into effect, switch the old policy to the Suspended state and switch the new policy to the Productive state. When you are certain that you will no longer need to revert to the original policy, switch it to the Retired state.

Switch the existing policy to the Suspended state, make the necessary changes to the policy and then switch it back to the Productive state. While the policy is in the Suspended state, it will not be enforced. (Because suspending the policy results in an enforcement gap, one usually does not use this approach in a production environment.)
