This question is similar to the question here.
Let us assume that I have made a Grails application and then, sometime down the road, I need to add a field to a domain class. What would be the best way to add that field and have all the objects already persisted to the database be updated too? Is there anyway to do this in Grails (currently using 1.3.7, but upgrading to 2.0 when it is stable) without manually accessing the database?
