[Virtuemart 1.1.9] Order management: export orders and reset current of the same

[robertosalemi]

Hello everyone,
work are Virtuemart 1.1.9, I would need to do the following:
1. Export of existing orders in the backend;
2. Clear the existing orders so as to start one.

For the first I had assumed an export in CSV table 'orders', would it work?
For the second just run a DROP table 'orders'?

What are, in your opinion, the two best ways to go?

Thank You.
