Can we upload Storyline files to Brainier LMS?
While I haven't heard of Brainier, Storyline supports AICC, SCORM 1.2, SCORM 2004, and Tin Can API (xAPI). More on Storyline's LMS publishing option here. As long as this LMS supports any of these standards, you should be good to go!
The community may have experience with uploading to this platform, so I'll open the floor to them!
