Changing MCU device in CubeMX for an existing project

I am developing a product using the NUCLEO-N657X0-Q dev board and have generated the configuration setup from CubeMX and developed the code in the CubeIDE.

When I need to layout my own circuit board I will want to use the STM32N657A0 variant which has 169 pins and I was wondering if I am able to use CubeMX to change the existing configuration done for the Nucleo board to the STM32N657A0 169 pin device without destroying the code I have already developed?

I have written the code using resources and pin outs available on the STM32N657A0 device but the actual pins are different on the two devices so need to know if I can make the transition using CubeMX or whether it will have to be done manually?
