I have a 24 foot above ground pool and two of the sides have dropped (they post appear to be sitting on clay and it has been very wet this year). The difference between the high and low side is about 8cm.

I would like to relevel the posts and put in paving stones but cannot find anything on how to do this.

I would prefer to avoid having to take the wall out. I have drained the pool, removed the old liner, dug out to level on both the inside and outside and I am now trying to figure out the best way to relevel the post and support the rail.

I know when installing a pool, they do not recommend building up a side, instead lower everything.

Thoughts and/or recommendations?

You are correct about not building up anywhere under the outer ring. However you can raise an area using a solid block or brick along the circumference of the ring, not just under the post. I am cofused by part of your statement. If you "dug out to level on both the inside and outside " why do you still need to relevel?

I dug out on the inside and outside to be able to see the bottom of the rail.

1/2 of the pool is buried on the outside. On the inside there is a level of crushed gravel and sand that is higher than the rail (as they either filled it in or just because the posts/rail sank).

One side of the pool is 4" lower than the other. Rather than lower the entire pool 4 inches I was wondering if I could meet in the middle or just raise the 'drastically' sunken part to a more reasonable overall difference.

I think the approach we are going to take is put each post on a 1' x 1' patio stone (so I have to dig under each post upto 2" on the higher posts and obviously very little for the ones I need to raise).

Thanks,

You idea may work but not just under the posts, put those patio stones all along under the rail too. You have several tons of water pressure pushing down evenly all over the floor of the pool, not just at the posts. Build up a sand cove to cover the pation stone or use a foam cove, this will protect your liner.
