PS4 admin?

I signed up the first account on my son when I installed the PS4. He is now admin. It wasn't until later that I took on myself as a father. I can't use it to manage my son's playing times. Since I unfortunately have to put my son in his place, I want to be admin myself. How can I do this without my son losing his scores and purchases? He has a PS Plus membership. If I upload his account balances to the cloud and then reinstall the PS4: can I first log in as admin, then set up a second account for my son and can he then download his saved games? Unfortunately, I don't play with the PS4 at all and don't know what could be lost.
