I currently use the BIAB 2014 UltraPlusPak. I bought the 2015 UltraPlusPak but haven't installed it yet.

With an eye on upgrading to the 2016 BIAB offerings, do I understand correctly, that if I

a) get the 2016 PlusPak for $99, and then the 49-Pak for $49,

that will leave me with all the same content (RealTracks, midi, the works) I'd have if I'd gotten

b) the 2016 UltraPlusPak?

Also ... I reckon that if I choose option a), then if I want to get my content up to date as described, I'd need to first install BIAB 2015 (to get then new content vs 2014) and then install the 2016 PlusPak and the 49 Pak, is this right? If so, seems I can pull this off without having to download anywhere near the 90 GB required for a fresh install 2016 UltraPlusPak.
