Not all the old ones have the same effects as the new ones.
Apricorns (What ball?) Effect.
Red Apricorns (Level Balls) Catch rate if the player's current Pokémon's level is:
* The same or lower than the wild Pokémon's: 1×
* Higher than the wild Pokémon's: 2×;
* Double or more than that of the wild Pokémon's: 4×;
* Four times as much or higher: 8×
Blue Apricorn (For a Lure Ball) Wild Pokémon must be hooked by a Fishing rod. (3x catch rate)
Yellow Apricorn (For a Moon Ball) Only if the wild Pokémon evolves with a Moon Stone. (IT IS NOT THE SAME AS THE DUSK BALL! Dusk ball is for catching Pokemon at night where as a Moon Ball catches a Pokemon that can evolve using a Moon Stone such as Clefairy.)
Green Apricorn (Friend Ball) The wild Pokémon has a happiness value of 200 after being caught. Catch rate is 1.5X
White Apricorn (Fast Ball) If the wild Pokémon is one that flees from battles. (For example, Abra, Magnemite, Grimer, Tangela, Mr. Mime, Eevee, Porygon, Dratini, Dragonair, Quagsire, Entei, Suicune and Raikou.)
Black Apricorn (Heavy Ball) Catch rate if the wild Pokémon is:
* Between 100kg* and 200kg*: +0
* Between 200kg* and 300kg*: +20
* More than 300kg*: +30
* Under 100kg*: -30
Pink Apricorn (Love Ball) If the player's current Pokémon and the wild Pokémon
have opposite genders.
Not to mention these Pokeballs have a different appearance compared to the new ones.

Hopefully, we can get our own Pokeballs back.
