How to transfer older network trending data
If you need to transfer trending data into Apex that is much older that what Apex currently has, you can do so. This allows you to view dashboards against much older reporting periods that, until now, you did not have trending data for.
To transfer older network trending data:
1. In the web interface, click Configuration > Data.
2. Select one by clicking a table row.
3. Expand the Trending Data Commands area.
4. Click either of the Time Range boxes
5. Set your date and time range, and click OK.
6. Click Get Trending Data Range.
The network trending data begins transferring to Apex.
Apex should now have the network trending data that you specified.
