Move Over
Move with him in that city.
When planning a move to the city, you should consider schooling options, taking care of your plants and pets during the move and moving expenses. You may also want to consider the differences of City and Rural lifestyle.
first you need fly which is at cleadon city then fly to fushia city and next to the Pokemon center there are two houses try them both and you desire what move should your Pokemon should forget
Visit the city once or twice before making the move. This way you have a chance to learn about the city and neighborhood at least somewhat before the move.
If you go to the Celadon City Department Store and buy a drink, then go to the guard, if you talk to him, he should take the drink. Then he'll move out of the way and you'll be able to get to Viridian City.
Vegas, baby.
Fly to Lillycove City, then enter the house next to the dept. Store and the move deleter should be there.
