We upgraded the routers at some of our locations. The new router has the same name and IP as the old one. The old router used an interface serial 0/0/0 as the WAN connection, the new routers use FastEthernet4. The issue is that the routers were swapped without removing serial 0/0/0 now when I go to List resources I dont see serial 0/0/0 as an interface. However if I look at the device it lists the interfaces on the device and the device now shows that it has serial 0/0/0 and FastEthernet4.
What is the easiest way to get rid of the serial 0/0/0 interfaces. This has now happened on around 100 devices. Could I do a sql statement to select devices that have both a fastethernet4 and serial 0/0/0 and delete the interface serial 0/0/0 somehow?
