What is the best way to update your Google datastore with new fields?

Question

I need to add new fields to existing tables. After adding fields, the application is interrupted because old records do not have a newly added field and throw an exception. Is there a way to update all old records with new fields?

I need this for a java application in google engine.

• Update existing rows in the datastore with default values ​​/ null for newly added columns

• . : catch try , , catch , 1 . .
