The root rot will only spread if the medium is too wet and lacking aeration. Most of your plant's roots still look in good condition considering that peat and coir can easily stay too wet. It looks like the pot is traditional clay which helps by permitting evaporation through the sides.
When you re-pot (using a gritty, free draining mix) you should only use a slightly bigger container. Going from 20 litres to 50 litres is likely to leave a considerable volume of new mix which can stay too damp because there are no roots to absorb moisture. Roots starting to try and penetrate this region are likely to rot.
