Split a domain and migrate change to database

I have a domain class and it already has a lot of data in the database. Now I need to split the domain into two. Is th开发者_JS百科ere a way by which the data in the database will automatically be split into the two tables as well?

You can use the Grails Database Migration Plugin plugin for such a task.

i think there is no automatic mechanism for your issue. i would backup the old database schema, change the domain class schema, deploy the new shema (hopefully all database changes get executed) and migrate the old data to the new schema.
