Why this matters
Odoo migration is not a copy-paste exercise. Moving data, custom modules, and business rules across versions, or from a legacy ERP, requires architectural discipline that most generalist partners skip. The eleven red flags below are the patterns we see repeatedly when a North American mid-market company inherits a...

If the partner cannot hand you a document listing every source table, target module, transformation rule, and owner before the project kickoff, stop. A real data migration plan names who extracts, who validates, who signs off on each business object, customers, open invoices, inventory moves, open purchase orders....

Custom Odoo modules written against v14 or v15 APIs can be incompatible with v17 or v19 in ways that are not obvious until the upgrade script runs. If your current implementation has custom modules with no documented manifest version and no test suite, budget at minimum two sprints just to assess them, before any new...

ERP migrations have a defined scope: data, configuration, custom modules, integrations, and training. Any partner who refuses to quote a fixed price after a thorough discovery is signaling that they plan to learn your system on your budget. Octura's approach, fixed-price scoping after discovery, is not a gimmick; it...

The cutover weekend is not the first time you should run the migration scripts. A full cutover rehearsal, ideally two, exercises the sequence end to end in a staging environment loaded with production data volume. It reveals timing issues, blocked operations, and data gaps that only appear at realistic scale. Partners...

Accounting data is the hardest to migrate and the easiest to get wrong in ways that only surface at month-end. Open invoices, payments, and journal entries must carry over with matching balances that reconcile to your trial balance in the source system. If the partner's migration spec does not include a signed-off...

UAT is not "click around and see if anything looks wrong." A real UAT protocol maps each business process to a test script, purchase order to receipt to vendor bill, sales order to pick to ship to invoice, and requires a named business owner to sign off before go-live. Partners who skip UAT or compress it to two days...

The architect you met in discovery is not always the developer who writes your custom module or migration script. Some partners sell with a senior face and build with an offshore team the client never meets. Ask upfront: who writes the code, what timezone, and what is the escalation path when there is a production...

If you use FIFO or AVCO costing, the opening inventory valuation in Odoo must match your source system exactly, quantity on hand times unit cost per lot or layer. Partners who import products without reconciling the costing layers are creating phantom gains and losses that hit your P&L immediately. A physical...

EDI connectors, 3PL APIs, payment gateways, and payroll systems cannot be deferred to after go-live without a clear interim plan. If an integration is "post-go-live," define exactly who runs the manual process it replaces, for how long, and at what operational cost. Integrations left vague become the longest-running...

Every go-live has a go/no-go decision point and a defined rollback procedure if the check fails. If the partner has not written down the rollback steps, what gets reverted, in what order, and how long it takes, they are planning to wing it if something goes wrong at 11 p.m. on Friday. The rollback plan should be part...

The most expensive red flag is also the most common: a partner who codes a custom module to solve a problem that standard Odoo Studio or native configuration already handles. Every custom module you carry into a version migration is a liability. Ask whether the solution was first explored as configuration before any...
Bonus
The eleven red flags above are mostly partner-selection failures that compound into technical disasters. Here is the short checklist before you sign any migration statement of work:
