Odoo Migration Services
Odoo upgrades are re-implementations wearing a friendly name. Between major versions the framework changes, standard behaviour shifts, and every line of custom code needs reviewing, porting or retiring. Done casually, migrations lose data and break workflows; done properly, they’re a rehearsed non-event.
We’ve migrated systems across versions 8 to 19, including heavily customised platforms where failure wasn’t an option: a 150+ merchant multi-tenant deployment and manufacturing accounting logic carried live across four major versions.
What the work involves
- Audit before anything. Every custom module, third-party app and integration is inventoried and triaged: port it, replace it with now-standard features, or retire it. Many customisations die here happily, because newer Odoo often absorbed the need.
- Data migration with reconciliation. Master data and open transactions migrate with integrity checks and count/value reconciliation at each stage. History depth is a scoped decision, not an accident.
- Staging rehearsal, then rehearse again. The full migration runs on staging with production data. Your team tests real workflows against a checklist. We iterate until the rehearsal is boring, because boring is the goal.
- Cutover with a rollback plan. A planned window, a step-by-step runbook, and a tested rollback path. Nobody migrates on optimism.
- Version-specific guidance. See the dedicated guides: 15 to 19, 16 to 18, 17 to 19, 13 to 17, plus Community to Enterprise and on-premise to Odoo.sh.
How the migration runs
- Audit and triage. Every customisation, module and data object inventoried and sorted: port it, retire it, or replace it with what newer Odoo now does natively.
- Fixed quote from the audit. The number arrives with an hours breakdown per module, before the commitment.
- Staging rehearsal with production data. The full migration runs end to end on staging, and your team tests real workflows against sign-off checklists.
- Reconciliation sign-off. Record counts and value checks per model prove nothing was lost. Evidence, not assurance.
- Planned cutover with rollback. A scheduled window around your trading calendar, a step-by-step runbook, and a tested way back.
Common questions
Should we skip versions or upgrade one at a time?
Skipping is normal and usually right (13 straight to 17, 15 straight to 19). The work scales with the customisation gap, not the version count, and the tooling supports multi-version jumps.
How much history should we bring?
Open transactions and a defined window of history migrate; deep archives often stay queryable in a read-only legacy instance. It's a cost/benefit call we'll make with you explicitly.
What does a migration cost?
It tracks your customisation surface. The audit phase produces a fixed quote with an hours breakdown, so the number arrives before the commitment.
Can we change processes during the migration or keep everything identical?
Both are valid strategies. Like-for-like is lower risk and faster; migration is also a natural moment to fix broken processes. We'll help you sort the must-fix from the nice-to-have so scope stays controlled.
What happens to our third-party apps from the Odoo store?
Each one is checked for a target-version release. Maintained apps upgrade with you; abandoned ones get a replacement plan before the migration starts, not during it.
