nrf_serial vs. app_uart

Question

I'm migrating to the new 13.0.0 SDK and I'm wondering what are the benefits of using nrf_serial over app_uart (if any) and what steps I would need to take to switch over if I choose to.

Hi, 
 The advantages of the Serial port library over UART library is described in the documentation : 
 
 This module allows to create and
handle serial port instances. It is
designed as a more sophisticated
replacement for the app_uart module.
The following are the advantages of
this module over app_uart: 
 
 API is more generic and robust: you can read or write any amount of bytes. 
 Multi-instance capability. 
 The module can work in three modes: POLLING, IRQ, and DMA. 
 Calls can be asynchronous and synchronus (with timeouts). 
 Independent RX/TX FIFOs with configurable sizes. 
 Configurable RX/TX transfer buffers (smallest transfer slice). 
 Event handler (not mandatory). 
 Sleep handler (not mandatory). 
 
 
 You can find an example of how to use the Serial library in the SDK. 
 Best regards, 
 Jørgen
