NAME
       KiokuDB::Role::Upgrade::Data - Classes that provide their own upgrade routine.

SYNOPSIS
	   with qw(KiokuDB::Role::Upgrade::Data);

	   sub kiokudb_upgrade_data {
	       my ( $class, %args ) = @_;

	       # convert the data from the old version of the class to the new version
	       # as necessary

	       $args{entry}->derive(
		   class_version => our $VERSION,
		   ...
	       );
	   }

DESCRIPTION
       This class allows you to take control the data conversion process completely (there is only one handler per class, not one handler per
       version with this approach).

       See KiokuDB::Role::Upgrade::Handlers::Table for a more DWIM approach, and KiokuDB::TypeMap::Entry::MOP for more details.
