Each Pokemon's saved data stores the original trainer and sometimes the location where it was found. So the migrated-to game knows you did not catch it there. All the Pokemon you caught in your game will have your unique ID just as well.
You can re-catch any Pokemon in Fire Red who are not the legendary. For example if you caught Moltres and trade it to your Sapphire game, then you CAN NOT go back to Mt. Ember and expect it to re-appear. But other Pokemon in the game who are not unique you should have no problem finding plenty of replacements.
