Version upgrades
Odoo releases new versions regularly. Standard configuration generally carries forward without difficulty. Custom modules do not: each must be reviewed against the new version's framework, updated where necessary, and re-tested. The effort scales with the size of your customisation portfolio, which is why the portfolio deserves governing from the start.
A version upgrade that goes well
- 1
Inventory the customisations
List every custom module and third-party module in use, with its publisher and last maintenance date.
- 2
Assess before committing
Have the partner review each module against the target version and estimate rework. Modules from unmaintained publishers should be identified here.
- 3
Upgrade a copy first
Perform the upgrade on a copy of production and keep it running in parallel while testing.
- 4
Test the customisations specifically
Standard functionality is tested by Odoo. Your custom modules are tested by you, against your real scenarios.
- 5
Retire what you can
An upgrade is the natural moment to remove modules whose purpose has passed, or whose function now exists in standard.
- 6
Plan the cutover
With a rollback position and a defined decision point for invoking it.
Migrating to Odoo from another system
- Master data — customers, suppliers, items, chart of accounts — is generally straightforward to load
- Opening balances are the recommended default; full transaction history is expensive and rarely necessary
- Where history is genuinely required, consider retaining read-only access to the legacy system instead of migrating it
- Data quality in the source system, not volume, determines the effort
- Profile the source data in the first two weeks, before configuration decisions are locked
- Reconcile every migration run against source totals with finance sign-off
Migrating from Odoo to another platform
Odoo's data model is documented and its API is well covered, which makes data extraction comparatively straightforward — a genuine advantage that not every ERP offers. What does not transfer is configuration, workflow and custom logic. Treat a move to another platform as a re-implementation with a data load, not as a migration.
Before moving off Odoo
- Diagnose whether the problem is the product, the implementation, or unmanaged scope
- Extract and archive your data while you still have a working system and, ideally, a working partner relationship
- Confirm the target platform genuinely solves the specific problem, tested against your own scenario
- Decide which customisations to carry forward and which to abandon in favour of standard process
- Budget internal effort comparable to a first implementation
- Keep the Odoo instance available read-only for a defined period after cutover
