Rusting, and staining liner, how to replace ?

[toyopl]

Moved into new house with 24ft pool, and I noticed there's rusting metal part that's just crumbling away, and staining the liner.
Can this be replaced while there's water in the pool ?
Not familiar with assembly of pool, so not sure what is it that's rusting, and how to go about changing it out.

Some pics may help us help u more. Does the pool have an overlap liner?

Which part? A metal top rail actually affixed on top of the wall itself? If so, you can remove two at a time.

So sorry, I forgot to add it in my original post, updates.
Thank you.

I'd plan on having to replace a couple of post cap plates that holds the rails in place and that the resin ledges bolt down to as well.

Hopefully its just the inner rails affected - inyopools.com has lots of parts for many different manufacturers you can contact them if u need help identifying your pool but i have a feeling most 24’ ones will work so long as they have the same curvature & dimensions.
They come in sections roughly the length of each top rail.

To replace them you need to remove 2 top caps, then the top rail, then the rusty rail.
When replacing give the wall behind the liner a peek to be sure you don’t have a larger issue.
Like Woody mentioned go ahead & get some extra caps & plates especially if yours aren’t resin incase u run across some rusty ones or damage anything while you’re at it.
