Hi @RGarner21,
While I have not made the transition myself, you should be able to get most of that information from the developer of the tool. Since the TII integration takes submissions to Canvas and sends them to TII for screening and then sends them back, you should be able to just view past submissions in Canvas as normal.
I recommend reaching out to TII support to see what information is available to be downloaded as I believe they keep records of everything submitted via your integration. You can check out their support site here.
To answer your question about blueprint syncs; Assignments are going to sync, though you will need to update the assignments with the new integration in your blueprint course. Changing the integration won't stop assignments from syncing, but it will likely cause those assignments to not function properly until they are updated in the associated courses.
