메소드	설명
NeedsRealMigration ( int startingVersionNumber, int endingVersionNumber ) : bool	An optional check for real data migration needs can be performed before calling PerformMigration by calling this method. If it returns `true`, then real data changes will be required to get from startingVersionNumber to endingVersionNumber.
PerformMigration ( IDomainObjectDTORepository domainObjectDtoRepository, int updateToVersion, IThreadedProgress progressDlg ) : void	Perform the data migration on the DTOs in the given repository. The resulting xml in the DTOs must be compatible with the xml of the given updateToVersion number. The implementation of this interface will process as many migrations, in sequence, as are needed to move from whatever version is in the repository to bring it up to the specified version number in updateToVersion. An implementation of this interface is free to define its own migration definitions. These definitions need not be compatible with any other implementation of this interface. That is, there is no interface defined for declaring and consuming data migration instructions.

Perform the data migration on the DTOs in the given repository. The resulting xml in the DTOs must be compatible with the xml of the given updateToVersion number. The implementation of this interface will process as many migrations, in sequence, as are needed to move from whatever version is in the repository to bring it up to the specified version number in updateToVersion.

An implementation of this interface is free to define its own migration definitions. These definitions need not be compatible with any other implementation of this interface. That is, there is no interface defined for declaring and consuming data migration instructions.

domainObjectDtoRepository	IDomainObjectDTORepository	Repository of CmObject DTOs.
updateToVersion	int	/// Model version number the updated repository should have after the migration ///
progressDlg	IThreadedProgress	The dialog to display migration progress
