Unfortunately, there isn't an import functionality for this but you could come up with the SQL statements using Excel's string manipulation functions. There are only2 tables you will need to insert these into. If you open the Database manager utility on your NTA server and browse to the netflow set of tables the table names are fairly obvious. You may need to restartthe Solarwinds Information Service for these to show up in the web console. Be sure to backup the tables first.
