How do you change Rotom forms in Pokemon X/Y?

I just caught Rotom, but it was the normal-form Rotom. I would like the Mow Rotom, but I don't know how to change it's form.

Is it possible? If it is, where can I change Rotom's form?

You can change Rotom's form in the 2nd floor of Sycamore's Lab, in Lumiose City.
