Archive old orders Magento Extension
With this extension you will be able to archive older orders so those are not shown on the “Sales -> Orders” grid.
The orders are not deleted, just not returned when you query the database for current orders.
You can see the archived orders on a new grid specially created for this orders.
To archive an order you have to select the orders from the Sales Orders grid and on the mass action select, choose “Archive” the selected orders will be then archived.
On a future version I will add the feature to automatically archive orders older than “X” days.
You can get this extension at the price of $ 69 american dollars.
