'If you hold a Category 6, 8, or Tier 1-3 legacy certificate, it's ideal to downgrade your certificate before converting so that points don't potentially get lost in the process.'

I'm not sure about this. When I redeem my Cat 6 cert I will be looking for a Cat 5 or Cat 6 property as repeatedly promised throughout the purchasing process. I won't be accepting a new Cat 4.
