Change Cirrus To Express Mode

The client asks me to go from cirrus to express mode. Do you know how I could do it? Is there any guide for it? Thank you!

Hi Juliofragio Do you want to back from a native ov cirrus paid account or else? Did you already form Express cluster before and if right did you have done proper backup of Express configuration on your APs? How many APs do you want to revert back? Hope this is helping

Thank you
