I recently updated WooCommerce on a site that I didn't make myself. After doing this, then I saw the following line in the error-log:

woocommerce_get_price is deprecated since version 3.0.0! 
Use woocommerce_product_get_price instead.

But when I google woocommerce_get_price, then I can find no documentation on it, besides for this hookr-page and this page, where it just says that it's deprecated. But I can find no information about input and output for woocommerce_get_price and woocommerce_product_get_price. It feels like that it's simply a renaming, - but how do I figure out, if I can simply replace the name of that filter, without having to test everything page and function on the website?

It's a function in a plugin that has been custom-made for this suppliers sites. And the function looks like this:

public function woocommerce_get_price($price, $product) {
    $price = $this->get_user_discounted_price($price, $product);

    return $price;

It's hard to find because the hook name is generated dynamically.

All the get_ functions in the WooCommerce product class, like $product->get_price(), use the get_prop() method under the hood. This is part of the WC_Data class that WC_Product extends. At the end of get_prop() the filters are applied like this:

apply_filters( $this->get_hook_prefix() . $key, $value, $this );

And get_hook_prefix() looks like this:

protected function get_hook_prefix() {
    return 'woocommerce_' . $this->object_type . '_get_';

So all the get_ methods like get_price(), get_sku(), get_description() etc. will go through a filter with the same format: woocommerce_product_get_{property}. In your case woocommerce_product_get_price.

For the new filter, the 2 arguments are the value, $value, and the product, $this. So it doesn't look like you need to change the callback. It should be sufficient to change the hook name.
