Transfer

Transferring is a process in which Pokémon are sent from one game to another without trading. The recipient game does not send a Pokémon back. Most commonly, transfers are one-way from a game in one generation to a game in a later generation (except in Generation IX where it is possible to transfer back to Generation VIII). The exact process usually differs for different generations.
==Precursors==
Transfers did not yet exist in Generation I or Generation II. Instead, these are the only generations to support trading between them.
The Time Capsule allows Pokémon to be traded between Generation I and Generation II, conceptually acting as a time machine bridging the three years between events in each generation. As with all Generation I/II trades, it requires two systems connected by a Game Link Cable, or via local wireless in the Virtual Console releases. It does not allow trading of any or any Pokémon that know moves introduced in Generation II.
Generation III is the only generation where there is no method to receive Pokémon from past generation games.
==Transfer methods==
Transferring was introduced in Generation IV and has remained in all generations afterward. Therefore, it is possible to transfer a Pokémon from Generation III to any future generation through a chain of transfers. With the Virtual Console releases of Generation I and games and an update to Poké Transporter in Generation VII, it became possible for the first time since Generation II to have Pokémon from all generations in a single game (though Generation I and II Pokémon still cannot be transferred to a generation between III and VI).
Pokémon that cannot be traded for technical or plot reasons also cannot be transferred, including Spiky-eared Pichu; the fused versions of , , and ; and the and partner .
===To Generation IV===
The Nintendo DS's dual-slot mode allows Pokémon to be transferred from Generation III games to Generation IV games. When a Generation IV game is started with a Generation III game in the console's Game Pak Slot, if Pal Park has been visited in the game, the option to "Migrate from [game]" will be available on the main menu. (Due to the removal of the Game Pak Slot for the Nintendo DSi and Nintendo 3DS, Pokémon cannot be transferred to Generation IV on DSi or 3DS consoles.)
Six Pokémon can be migrated at a time and, in , Pokémon can only be migrated once every 24 hours. In the destination game, the migrated Pokémon will be available at Pal Park for the player to catch in a Catching Show. The Park Balls used in Catching Shows always capture a Pokémon when thrown; however, Pokémon captured during the Catching Show retain the kind of Poké Ball they were caught in in a Generation III game.
This is the only generation where transferred Pokémon retain their held items.
===To Generation V===
In Generation V, there are two methods of transferring Pokémon from Generation IV: Poké Transfer and the Relocator. Poké Transfer is the general transfer method, while the Relocator is a special method of transferring a few specific event Pokémon. Either method requires two systems and uses the system's built-in wireless communication.
Poké Transfer is used by visiting the Poké Transfer Lab on in a Generation V game. A at the back of the lab will allow the player to start Poké Transfer on their game, at which point a system with a Generation IV game must be started and the Poké Transfer application must be selected from the system's DS Download Play option. Six Pokémon can be sent to the Generation V game from the Generation IV game via the downloaded application. These Pokémon must then be captured in a time-limited slingshot minigame; any Pokémon that are not caught will remain in the Generation IV game.
The Relocator is only available in . Only the , distributed to commemorate the thirteenth movie can be transferred with the Relocator. The Relocator can be found in Castelia City and must be unlocked with the correct keywords.
===To Generations VI and VII (excluding Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!)===
Pokémon Bank and its companion application Poké Transporter are used for transfer to the Generation VI games and the 3DS Generation VII games. Transfer from multiple generations is possible:
* Pokémon from the Virtual Console releases of Generations I and II can be sent to Pokémon Bank through Poké Transporter, and may be withdrawn in Generation VII games.
* Pokémon from Generation V can be sent to Pokémon Bank through Poké Transporter, and may be withdrawn in Generation VI or VII games.
* Pokémon from Generation VI can use two-way transfer with Pokémon Bank. This also applies to Pokémon that originated from Pokémon Bank distribution events during Generation VI. However, once a Pokémon has been withdrawn once in a Generation VII game, it cannot be transferred back into Generation VI.
* Pokémon from Generation VII can use two-way transfer with Pokémon Bank.
Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! are incompatible with Bank and other Generation VII games under all circumstances.

Transfer restrictions:
* Cosplay Pikachu cannot be deposited into Pokémon Bank (but may be traded with other copies of Pokémon Omega Ruby and Alpha Sapphire).
* Totem-sized , , , and cannot be deposited into Pokémon Bank (but may be traded with other copies of Pokémon Ultra Sun and Ultra Moon).
===To Generation VIII and IX (as well as Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!)===
The following transfers are possible:
* Pokémon from Pokémon Bank can be sent to Pokémon HOME, and may be withdrawn in Generation VIII.
* Pokémon from Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! can use two-way transfer with Pokémon HOME. However, once a Pokémon has been in a Generation VIII or IX game, it cannot be transferred back into Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!.
* Pokémon from Pokémon GO can be transferred to Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! through the GO Park, and to Pokémon HOME through the GO Transporter. Pokémon from the GO Transporter can be withdrawn in Generation VIII or IX, assuming it exists in the game data.
* Pokémon from Generation VIII and IX can use two-way transfer with Pokémon HOME. This also applies to Pokémon that originated from Pokémon HOME distribution events during Generation VIII or IX.
Source 	 	Transfer method 	 	Destination
Bank 	→	HOME 	→	Gen VIII and IX
Let's Go	→	HOME 	→	Gen VIII and IX
Gen VIII	→	HOME 	→	Gen IX
Gen IX 	→	HOME 	→	Gen VIII
GO 	→	GO Park 	→	Let's Go
GO 	→	GO Transporter → HOME	→	Gen VIII and IX
In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! and Generations VIII and IX, not all Pokémon and forms exist in the coding of each game, and HOME will only permit a Pokémon to be withdrawn if both the Pokémon and the specific form exists in the coding of the destination game. Compatible Pokémon for a particular game may be expanded with updates over time.
The following 12 Pokémon lack a compatible game in Generations VIII and IX, and cannot be withdrawn into any of those games at all:
Additional transfer restrictions:
* Gigantamax Factor , , and cannot be transferred to Pokémon Brilliant Diamond and Shining Pearl, , or .
* cannot be transferred in either direction between HOME and Brilliant Diamond/Shining Pearl.
* originally from Brilliant Diamond/Shining Pearl can only be withdrawn by those games, and Nincada originally from outside of Brilliant Diamond/Shining Pearl cannot be withdrawn in those games.
* If one Brilliant Diamond/Shining Pearl save file has more than one of a Pokémon species that is normally only catchable once per save file (such as or ), and neither has been deposited into HOME before, only one may be deposited, even if they have different OTs.
These restrictions occur for a variety of technical and glitch-prevention reasons (see the Limitations section of the Pokémon HOME article for details).
====Moveset alteration====
Similar to the situation between the Alola 3DS games and Let's Go, Pikachu!/Let's Go, Eevee!, the paired releases of Generation VIII and IX have significant coding differences, and thus cannot directly battle or trade with any game outside of its pairing. In this sense, the generations are split into four "game environments": Sword/Shield, Brilliant Diamond/Shining Pearl, Legends: Arceus, and Scarlet/Violet.
Different game environments also have different move lists. To allow Pokémon to be transferred between them despite these differences, Pokémon HOME tracks the game-specific data of each Pokémon, and assigns appropriate movesets whenever the Pokémon's game environment changes. 
* If a Pokémon enters a game environment that it has never been in before, it will be assigned a moveset of its 4 most recent level-up moves in the destination game.
** Example: a level 20 caught in Sword is transferred to Brilliant Diamond. Upon arrival in Brilliant Diamond, the Pikachu will have a moveset of , , , and .
* If the Pokémon returns to a game environment that it has previously been in before, it will regain its previous moveset data for that environment.
** Example: if the Pikachu from the previous example is transferred back into Sword or Shield, its moveset from the last time it was in Sword or Shield will be restored. If it is transferred into Brilliant Diamond again, its moveset from the last time it was in Brilliant Diamond or Shining Pearl will be restored.
