[Star Wars] how did the imperial army turn from clones to all stormtroopers so quickly?

I'm playing Jedi: Fallen Order which takes place about 5 years after order 66.  The entire imperial army is now all stormtroopers, and I'm assuming it has been so for a long time before these events. How did this happen in such a short turn around. There would have likely been 100s of thousands to millions of leftover clones. How did they recruit so fast. How did they even replace all the republic gear too? They decommissioned perfectly fine venetor starships even. What a waste.

The Imperial Army isn't clones - it's recruits. The Stormtroopers are not the Imperial Army, they are a different military tradition.

The Empire spent the five years after the end of the Clone Wars building a massive recruitment system, phasing out the clones to the point where by the time Fallen Order takes place, seeing clones was a rarity.

They decommissioned the Republic ships because the Empire *was not* the Republic, although it was spawned from the Republic, the tactics used by the Empire are ironically closer to the way that the CIS operated - nameless, faceless ranks of soldiers taking power through sheer numbers.
