validation-overrides.xml can be added to the root of an application package (i.e. next to services.xml) to allow a deployment that otherwise fails to validate to proceed. Validations which can be overridden in this way are returned with a dash-separated validation id preceding the validation message, e.g if the message is field-type-change: Changing the type of field 'foo' to 'bar' is not supported the validation id is field-type-change. See ValidationId.java for a list of available validation overrides.

Validations protect against inadvertently corrupting a production instance. Overriding them may be useful e.g if the application is not in production yet or if you think the consequences of inconsistencies or loss of the data in a particular field are fine.
