In this phase, Odoo migration experts define how each dataset will map from the old system to the new to avoid data inconsistencies. This step maintains referential integrity and makes sure that related records remain connected in the new system. Experts securely transfer all your business data, such as customers, sales orders, invoices, payroll details, attachments, workflows, and custom fields. They also create a data migration blueprint to give you a clear overview of the sequence of tasks, dependencies, task deadlines, resource allocations, and risk assessment plans.
