Redeploying a Virtual Service
A virtual service that is already deployed on a Mediator can be manually redeployed. You can redeploy a virtual service using the same deployment mechanisms mentioned above. If you make changes to a virtual service's processing steps, for example, you must manually redeploy the virtual service to put those changes into effect.
As described in
Modifying a Run-Time Policy, you cannot make changes to a run-time policy while it is active. To make changes to a policy after it has been switched to the active state you must do one of the following:
Switch the policy to the Suspended state (to deactivate it), update the policy and then switch it back to the Productive state (to reactivate it).
Create a new version of the policy, make your changes to the new version of the policy and then switch the new version to the Productive state. Switching the new version of the policy to the Productive state will automatically Retire (and deactivate) the old version.
If you need to update a run-time policy that is already deployed with virtual services that are in production, always use the second method described above (that is, create a new version of the policy). If you use the first method, which requires you to suspend the existing policy, your production services will be running without the policy while you are making your revisions to it.
