The following scripts and commentary are a general guide that I created while migrating a customer from SugarCRM Community Edition with the Advanced OpenSales plugin to SugarCRM Professional using the built-in Quotes and Products modules. It's not perfect, and your mileage may very, but I hope it assists someone else as a solid starting point for a similar migration from AOS/SuiteCRM back to SugarCRM Pro.
These scripts ignore the PDF Template and Contract functionality from AOS. These were not relevant to my project, so I have no reason to attempt them.
