Two engagements, in detail.

Case A

A regulated waste-oil to biofuel operator · ongoing

A .NET CRM migrated to Odoo. Month-end reports matched.

Ongoing

ASP.NET Core · MariaDB
→ Odoo 19

Live. Both systems maintained.

entities migrated: 45+
reports migrated: 60+
master records moved: 1,000+

Parallel run. Month-end reports matched.

Our team migrated an ASP.NET Core and MariaDB system to a custom Odoo 19 addon. Both systems ran side by side until the month-end reports matched exactly. The .NET system remains in production for the records it still owns. Both systems are maintained.

Illustration: a month-end comparison sheet with sample report rows, each showing its .NET value and its Odoo value (not shown) and a difference of 0.00; the total difference is 0.00.
