How we can archieve order in hybris with all references. Or I need to write custom code to achieve this.

I have millions of orders in hybris and I want to archieve the orders which are 6 months old. By making this change load on order table will be very less. Please suggest if hybris provides some inbuilt functionality to achieve this.

Or I have to create all archieve classes in hybris similar to order / order entry or all related stuff.
