Buds are appearing in October - can I repot?

[Agrias]

Thanks It is not exactly soil, but it is not normal "orchid bark" i saw in some photos either...it is what it came from Ikea with, i have no clue of what it is - same with the pot

After I took the picture I noticed 2 new roots are growing, one is visible on the first pic.

I am watering it once a week, now stopping because it started getting cold.

When i talked about cutting i wasn't talking about cutting the cane, but the stalks from where the flowers were before so new ones can grow

If i repot, do i cut all those dead roots? Or should they stay?
