Difference Between NetFlowV9 and Flexible NetFlow

[MarcusMapes6844]

• Im getting a little confused. Is netflow version 9 flexible netflow? I watched a configuration video by solar winds that covered the config of "original netflow, netflow v5, and netflow v9" but didn't cover flexible netflow.
  Then on another video by them, its how to "configure netflow v9 AKA flexible netflow"
  So contradicting. don't understand. halp.

• I thought they were different. Like v9 has a bunch of different templates with different Collect and match options, and Flexible was basically custom made templates.
