What is the best practice for updating Banks and Bank Branches after a bank merger has occurred?

Summary

We need to update the Bank Branch (routing number) to another existing bank post merger of the two banks. What is the best way to do this?

Content

We have encountered several banks that have merged recently.  The surviving bank has taken over the routing numbers/bank branches currently associated with the non-surviving bank.  I would like to know what the best practice is for updating the bank and bank branches without losing the bank account associated with suppliers for payables invoice payments.  

Thanks, 

Judy
