Modifying payment accounts after payment was made

Good day all

I am starting my own business and I have started using erpnext. Got into the process of buying
i.e. material request , purchase order , purchase invoice , payment. One thing I did not pay attention to was the accounts that was used when a payment was made. Now there are payments that is made from one bank where it should accually be another bank. Is it possible to change this ?

Many thanks in advance
