Vandy's are sensitive to room placement. The owners manual provides clear information on placement based on room geometry. I have a pair of Vandy 2ce signatures in a 13.5'x 15'5 room, placed against the short wall. I found the best sound with my speakers are 32" from side walls and 30" from rears.
The Vandy's also image best when nothing tall (equipment rack, TV, or furniture is located between the speakers.
Unless your room is very small or you have a lot of stuff in between your speakers, they should do ok.
I would not expect the placement location of your current speakers to work best for the Vandy's, given how close you had them to your side walls and how far in front of your rear walls.
