Prestashop database job

An existing Prestashop with Multishop configuration (2 shops by now) has to be splitted into two single shops. This should be done via a script executable at any time, because the downtime of the two shops must be as short as possible. So the job would be: 1. Copy all settings from all tables with multishop functionality to the default tables for all settings (theme, positions, payment, shipping, domain, custom pages), products (quantities, prices, vat rules), modules and so on. 2. Delete the other shop (+ all multi shop relevant details from all tables) and disable the multishop functionality I am expecting an SQL script which can be executed with the target shop id as parameter. The plan behind this would be to copy the current mutlishop database 2 times and run the script against each of them with the corresponding id. That way, I should get two clean databases in a few seconds and the downtime would be minimal. You would get a copy of the database to work on, so you wouldn't need to access the live one.
