Database Conversion Joomla Virtuemart

1. I have Joomla 1.0 and the latest Virtuemart on one server where I receive my store data feed from my store Point of Sale inventory system (currently they will not move to Joomla 1.5) (server 1) It will not be live to the public...but I have to use it to obtain my data 2. I have the latest Joomla 1.5.12 with and latest Virtuemart 1.13 on another Server (server 2) This will be my live site because I want Joomla 1.5 features.... Server 1 I need a mysql query or script that will convert the database from server 1 Joomla 1.0 to the Joomla 1.5 format without breaking the product tables. I will have to do this manually on a regular or as needed basis or maybe set up as a cron.
