Linered or concrete style changes are relatively similar.
Linered. Remove liner, cut with a diamond blade the bottom leading to the deep end. Break the entire bottom into pieces. Dirty fill it leaving gravel on the top couple inches. Pour surface. Measure again for liner to bead (triangulation measuring is recommended A/B). If the bottom is to be a sport pool you may want to remove the entire bottom and dig it out a foot then pitch the wall 12/12 to the depth desired.
Concrete; similar except you need to bond the bottom sections so they dont split away with metal rods drilled in it as binders. Obviously etch the original concrete surfaces with muriatic acid so the new pour adheres. Bottoms on many concrete pools are poured after the walls in my experience retrofitting. If they are built otherwise you may need somebody else to advise you. This type of pool is rarely dropped an additional foot across its length and instead done as two tiers; one for children and another for adults with a net in between for volley ball, etc.
If you have more specific questions; feel free.

Why is a diving pool deeper than a swimming pool?
A diving pool is deeper than a swimming pool to ensure the safety of divers, as they need sufficient water depth to safely enter the water from heights without risk of injury. The standard depth for a diving pool is typically at least 3.5 meters (11.5 feet), allowing for safe landings from various diving heights. In contrast, swimming pools are generally shallower, as they are designed for recreational swimming and do not require the same depth for safety. This difference in depth accommodates the specific activities and safety needs associated with diving.
Why is diving in to a swimming pool easier than a block of ice?
diving into a swimming pool is not hard because water moves and ice is hard and you will heart your self if u try to jump in ice
