    Best way to upgrade/replace a node and retain historical data?


      When I have SiteX and I want to upgrade the router from a Cisco 2600 to a Cisco 2800, I want to retain all of the historical WAN throughput for that site.  What is the recommended way for doing that?  If the old router had Serial0/0 and the new router has Serial0/0/0, it creates a new interface under the new router in NPM.  Is there a way to take the data from Serial0/0 and combine it into Serial0/0/0?
