Answer 1

Are you using some kind of ORM? Hibernate maybe?. All in all workflow should be the same no mather how are you going to achieve this and is as follows:

1. Fetch some data from source DB(maybe single row with it's all associations.
2. Transform data into new database model
3. Save new modeled data into new database.

For fast transfer I would suggest to dump old DB, and create temporary instance on machine where your new DB server is located. Mysql provides fast serverside transfer od DB dumps between MySQL server instances.
