SecurityAssist is a lot less complex. Remember that only the interfaces that interact with the database have to be re-written. For DataAssist that was dozens, for SecurityAssist it is only a couple. SecurityAssist uses DataAssist for the registration and update user profile pages, so those are basically done and just need to be ported over. The authenticate user server behaviors already exist in mysqli, they just need upgrade paths. A lot of what we did in DataAssist will translate into a faster update for SecurityAssist.
