sorry for the [Urgent] but it is...
I hope your indulgence.

It's time to go online for our shop...

So I'd like to clean all the database infos gathered during development tests.
I have already deleted dummies products but now I need to clean orders.
1°On backend I changed the order statuts to 'Pending'. And then deleted them. OK
2° With phpMyAdmin I see that `jos_vm_orders` is empty now.
But I should reinitialize increment by this SQL command :
ALTER TABLE `jos_vm_orders` AUTO_INCREMENT =1
3°But 3 tables created by Phoca are still with old datas :
`#__{vm}_bills`
`#__{vm}_deliveries`
`#__{vm}_delivery_item`
Should I delete all the datas from these 3 tables and then reinitialize increment ?
Is it safe ?
No other tables to clean ?
Thanks for your help.
