Just bought a used copper canyon doughboy pool 16x32. No liner, No pump 6 years old

I have had an 26' intex pool for 5 years and we love it so much that we bought my uncles copper canyon doughboy pool 16x32 with a 7' deep end. We want something more permanent, and want to put this in the ground, but we don't know if we can put it all the way into the ground, and if our 2 yr old intex pump and sand filter will work. Any information would be greatly appreciated. We are going to try to do it all on our own. I have been researching for hours on how we should put this pool in the ground. Does anyone know if I have to use slurry?
