Mostly it's the technology that is the big difference... using an SDK installed in the app, with greater reliance on the developers...  while yes this can be connected to Launch, you can't run JS or do a lot of manipulation of the data, there is no DOM to read, etc...    For your specific questions:...

Lol, yeah, that was a pretty quiet sunset...  I know that Adobe has recommended Global Suites over Roll-Ups for years... it's not surprising that they were killed off... I haven't used a roll-up in about 15 years....  and even then, I barely used them since the data was so limited.

The documentation for "Roll Up Suites" seems to be gone, following the links inside the Adobe site actually just takes me to a page that talks about Global Suites...    I assume it's been dropped, since they weren't great to start with... and with the ability to do Global Suites with Virtual Suite b...

I'm really not sure what to say to that... Data Warehouse is very much alive in Adobe... and even the API you mentioned below is just a way to access the Data Warehouse without using the UI...    Maybe you are talking about the switch over from the old UI to the new UI?

What do you mean the Data Warehouse is deprecated? It's not deprecated... this is part of the tools available to you, there is no sign of it being removed... 

The API is part of the 2.0 designation, so I wouldn't think that using the API is legacy at all...  the legacy part is really just pertaining to where you are sending your data... FTP is less secure than some of the other methods... but if you aren't sending PII, the risk is pretty low... it's not r...

You can access FTP through any client side FTP tool, I like Filezilla (you only need the "client", not the "server" version), and you can log into FTP using the same credentials that you used in your Data Warehouse Export.   As others have said, FTP is legacy, but I still use it for quick and easy o...

Hmm odd... can you just add Orders (without the attribution)... I wonder if those "NONE" were set before your time frame...   Last Touch Orders against Marketing Channel are already "30 Day Attribution" (if you Marketing Channel Expiry is the default 30 Days).. but adding the 30 Day attribution I wo...
