earlier we were using netflow version 7 and now we have upgraded to version 9.8. since we have two versions of netflow our routers are configured to export IP flow to both the destinations. Also both are configured with exactly same alert profiles and they also send out an email if the alert is generated. I was assuming to receive two emails and should see the same alerts on both the versions but this is not the case. I can see most of the time alert is generated on only either of the versions very few times same alert is been seen on both versions and also I have never received alert emails from both the versions.

In future I am planning to use only version 9.8 but before I take off version 7 I have to make sure new one is working exactly the same as the old one.

I am not sure if this is how it behaves if you have devices configured for two netflow destinations. 

Any help will be highly appreciated.
