NO it will not so don't worry once you migrate it the data is on your diamond or pearl it will not go away. You can trust me because I transferred all my Pokemon from my emerald leaf green and sapphire to my diamond.
Pokemon cannot be transferred from Diamond to Leafgreen. This can be done backwards, however as Ruby, Sapphire, Emerald, Firered, and Leafgreen Pokemon can be permanently transferred to Diamond, Pearl, Platinum, Heartgold, or Soulsilver.
if you have Pokemon firered,leafgreen,emerald or ruby in you GBA slot with suciune in the game go to pal park go inside this grassy runny thingy and run around the field and you'l have your suicune migrated to Pokemon diamond
Migrated Pokemon are the ones you can catch at Pal Park after you transfer them from FireRed, LeafGreen, Emerald, Ruby or Sapphire games for the GBA.
IT IS NOT IN POKEMON DIAMOND OR PEARL BECAUSE IT IS ONE OF THE STARTING POKEMON IN LEAFGREEN!!!!! Migrate one from firered or leafgreen.
No. It was introduced in Pokemon Diamond and Pearl
you don'tyou use Pokemon firered and/or leafgreen to get the Pokemon migrated across
Sandshrew is not obtainable in Pokemon pearl/diamondzsemicolumz it must b migrated from Pokemon leafgreen/firered.
Infernape does not exist in Pokemon LeafGreen. Infernape didn't exist until Diamond/Pearl/Platinum, which was released after LeafGreen.
It's not possible to trade between Diamond version and Leafgreen version instead a feature called Migrating was introduced in Diamond utilizing the GBA slot in the DS console. Put Leafgreen in this slot and turn on Diamond and press start on the title screen and you should see an option called Migrate from Leafgreen. Press A on this option and follow the onscreen instructions in order to migrate. It's important to save both games in a pokemon center as well as have the pokemon you want to migrate in the PC rather than in the current party. One last very important note:You must obtain the National Dex in both games as well as give the Ruby and Sapphire items to Celio in Leafgreen. To get the pokemon you migrated go to the Pal Park in Diamond and you will be given Master Balls to capture the migrated pokemon. Run in the grass and water to find all your pokemon (only water pokemon will appear on water and some require a fishing rod to be used). After capturing them they will appear in the PC. Remember that only 6 pokemon can be migrated at a time and pokemon with HM moves cannot be migrated so make sure to remove these moves and lastly migrating can only occur once a day (if you change your DS time you can migrate whenever).
you cant you have to migrate it from Pokemon firered/leafgreen
You cannot see it in the wild in Pokemon Diamond; you have to transfer it from FireRed/LeafGreen.
you cant sorry but u can go from leaf green to diamond
