does NTA v4.0.1 support netflow v10
Yes, NTA 4.0.1 supports NetFlow v10 (aka IPFIX) format. However it doesn't correctly parse variable length flow fields, so make sure your template/record doesn't contain such fields (usually some device proprietary or text value). List of fields required to be sent in flows is here: SolarWinds Knowledge Base :: Required flow template fields.
For future reference, the variable length fields compatibility has been added in NTA 4.1 release.
