How would you start designing a low pass IIR filter? How long would it take you? Thank you!

Hi Matlab Fam, I wanted to design IIR low pass filter. There is an already designed FIR filter and need to extract the coefficients from there via FDA tool. This is being done to minimize the memory usage. I need to prepare the model as stable as possible and provide a report for it. I am taking this as a challenge and never did it before. Currently doing my desktop search.My question is: 1. How would you begin and what procedures would you follow? 2. On average, how long does it take till implementation and documentation? 3. Any sources if you can share would be highly appreciated!

If you know the transfer function of the filter/filter coefficients, you can start with the Discrete Filter block in Simulink.
Or if you know about the temporal behaviour and order of the filter, you can start modelling the equation in Simulink. For example
y(n) = A0*y(n-1)+B0*x(n)+B1*x(n-1)
