I wondered if you had fromd loss too. I think I tried bringing it indoors once.
I opted to keep mine in its current pot permanently (it is heavy to keep hauling around as is), so a bigger pot won't help me in that sense. It does lose some fronds in the winter, but I just cut them back come Spring.
Do you see keeping it in its current pot an option and just cutting it back in Spring as needed?
Let me try tagging someone to see if they can answer your original questions.
