abstract void downgrade	(	EOEditingContext	editingContext,
		ERXMigrationDatabase	database
	)			throws Throwable [pure virtual]

See also:

IERXMigration.downgrade

Parameters:

	editingContext	the editing context
	database	the migration database

Exceptions:

Throwable

if anything goes wrong

Implemented in Uber0, Uber1, RestExample0, BugTracker0, BugTracker1, ERAttachment0, ERAttachment1, ERAttachmentMigration, ERCoreBusinessLogic0, Movies0, Movies1, Movies3, ERTaggable0, ERTaggableEntity0, and ERXTest0.

void downgrade	(	EOEditingContext	editingContext,
		EOAdaptorChannel	channel,
		EOModel	model
	)			throws Throwable

Called when migrating the database from the next version to this version. For instance if this is AuthModel1, it will be called to migrate from version 1 back to version 0.

If this is the lowest migration you support, downgrade should throw an ERXMigrationFailedException.

Parameters:

	editingContext	the editing context you can perform EO operations with.
	channel	the channel to perform low level operations with
	model	the model being downgraded
