I have a set of virtual services deployed to the mediator. I plan to create a new run time policy for logging request/response payloads. From what i understand (centrasite 8.0) i would have to undeploy all of my services, and then redeploy them (run-time policy is applicable to ALL services). Is there a way in which i can hook up the policy with the existing services without undeploying them ? If not, are there any best practices around this ?
