Oncidium ampliatum Repotting

[AU77]

I bought this orchid in a bagged 4-inch pot yesterday at Lowe’s. It was wrapped in sphagnum moss and had pieces of styrofoam in the bottom.

I am planning on repotting it in a 6-inch clay pot with medium course orchid bark. I have never had an Oncidium before but know they don’t like wet roots. What do you think of this plan?

It will summer on my back porch with filtered morning sun. We have very high humidity here in the summer. It has been getting very hot, so I turn on the ceiling fan for air circulation.
