Apologies in advance for for the newbie question!

We recently replaced a Cisco 7200 with a Cisco ASR. This resulted in interface configuration changes gi0/1 on the old 7200 is now gi0/0/1 on the new ASR, etc.

As a result netflow analyzer is now producing graphs for dead interfaces. Based on the output of a "show ip flow export" the device is definitely exporting flows. 

Do we need to completely tear down the current netflow settings and rediscover the device? if so, how?

We are currently running version 9.5 (professional version) of netflow analyzer.

Thanks in advance!
