Replacing Stack member switches

[NetworkEng]

Hello Friends,
I have a stack members of four HP A5500 series switches in a stack fashion, I want to replace the whole stack with four new HP 5520 series product number R8M29A.

Replacing a stack of HP A5500 series switches with a new stack of HP 5520 series switches involves several steps, including preparing the new switches, transferring the configuration, and testing the new stack.Since this is my first time replacing a whole stack.
How can I proceed?
