How do you input codes manually like that? If the caught data is correct, there shouldn't be any reason that I can't transfer it to Gen VII, since that's the whole point of the vc versions.No it won't go away if you trade them to G/S but you can use this code to remove the data
[Remove caught data 1. party slot]

Use this code like the shiny code on page 3
But the data shouldn't you bother much because I think it will not be transfered to Gen VII games.
