LVL Span Ratings and Beam Placement
A multi span joist with intermediate bearing (3+ points of bearing) can clear span more than a simple/single span joist (2 points of bearing.) One span benefits from having the other span connected to it. 

Your dropped LVL is called intermediate bearing. It is typically sized to L/360 live load deflection, and the floor tributary is 5/8 of the joist span because of the added load from continuity.

When you flush that LVL, you typically size it to L/480 live load deflection, but you only use 1/2 of the joist span as the floor tributary. Obviously you have to cut the joists, so they can't span as far as joists that are continuous over the LVL. 

These small differences mean that sometimes it matters if you flush or drop the beam. Just make sure you check the joist span works as a simple span, and that the LVL deflects less than L/480 live so that you don't reduce the floor's performance. 

In my experience, going from dropped to flush with the same size LVL (which is what you're doing) works 90% of the time. You still need to check it though. 

Doing the opposite and going from flush to dropped can add 1/8 more floor tributary to it, so it's more likely to fail in moment or shear with the added load.
