Have a live production web store running Magento 1.5.0.1. Looking to upgrade to 1.6.2.0. I expect this to be done in a test environment first, THEN on the live website. Please be VERY knowledgeable of Magento and its database, and have done magento upgrades in the past… (Budget: $30-$250 USD, Jobs: Database Administration, Magento, Shopping Carts, SQL)
