Those very high leaves and roots are called keiki, which is a Hawaiian word for baby or child.
They are new plants and can be removed and potted separately. Cut the stem about a half inch below and above the keiki and re-pot.
After two years it is time to also re-pot the mother plant. Medium breaks down in the pot and needs to be replaced.
Remove the mother plant and clean off the old medium. Cut off any dead or soft roots and replace it in the same pot. It does not need a larger pot.
It has done so well for you use the same type of potting medium. It probably is a mixture of several types. If you are not sure post another photo and we will try to help.
