This document outlines a script for migrating Odoo instances between versions. It discusses why migrations are needed, such as upgrading or downgrading Odoo versions. It describes challenges like migrating business logic and data. The script is designed to make data migration easier by moving attachments and allowing unlimited migrations between local and remote instances regardless of Odoo or PostgreSQL versions. A demo of the script is provided and contact information is given for questions.
