Actually, now that I think back on my process, I don't believe that I used X-ray to bring the model into SDE. I created an empty file geodatabase, and used X-ray to load in the schema and set the spatial references on the datasets. I then brought all of my necessary data into that geodatabase. From there I just brought over each individual dataset that I needed into my SDE database. Like I said, it wasn't a very straightforward process, but it got me where I needed to be.
