Odoo releases a major version each year, and Odoo 18 — the current Long Term Support (LTS) release — brings meaningful improvements across the UI, performance, and core modules. For businesses still running Odoo 16 or 17, the question is no longer whether to upgrade, but how to do it without disrupting operations.
As an Odoo Partner implementing Odoo 18 and Odoo 19 for clients in India and North America, KometCode has guided several businesses through this transition. Here is what we tell every client before an upgrade begins.
What is new in Odoo 18
Redesigned interface
Odoo 18 ships with a cleaner, more responsive interface. Navigation is faster, the kanban and list views have been refined, and the mobile experience is significantly improved. For businesses where staff access Odoo from the warehouse floor or remotely, this matters.
Spreadsheet and reporting improvements
The embedded spreadsheet tool — introduced in Odoo 16 — is substantially more capable in version 18. Pivot tables, conditional formatting, and direct links to live Odoo data make it a viable alternative to exporting data to Excel for reporting.
Inventory and manufacturing updates
- Lot/serial number traceability has been simplified. Batch picking and FIFO/FEFO strategies are easier to configure.
- Work centre scheduling in manufacturing now integrates better with employee calendars, reducing scheduling conflicts on the shop floor.
- Quality control integration is tighter — quality alerts can now block downstream operations automatically.
Accounting enhancements
Bank reconciliation is faster due to an improved matching algorithm. Multi-currency handling and the intercompany workflow have been refined, which matters for businesses operating across India and North America.
Website and eCommerce
The website builder is more powerful, and product catalogue management from within Odoo has improved. For businesses running their online store through Odoo Website, Odoo 18 reduces the friction between back-office operations and the customer-facing store.
What to check before upgrading
1. Custom module audit
This is the most important pre-upgrade step. Every custom module needs to be reviewed against the Odoo 18 API. Some customisations may work without changes; others will need rework. Running the Odoo upgrade script on a test environment early identifies compatibility issues before they affect your timeline.
2. Data quality review
Upgrades expose data problems that may have been invisible in your current version — orphaned records, duplicate customers, inconsistent chart of accounts entries. Cleaning data before migration is far easier than cleaning it after.
3. Integration dependencies
If your Odoo is integrated with third-party systems — payment gateways, shipping carriers, custom APIs, or external databases — each integration needs to be tested against Odoo 18. API changes between versions can break integrations silently.
4. User training plan
A version upgrade is a natural time to retrain users on improved workflows. Budget 2–4 hours of role-specific training per user group, focusing on what has visibly changed rather than a full ERP refresh.
5. Go-live timing
Avoid upgrading during your busiest period. For retailers, avoid year-end. For manufacturers with peak production seasons, plan the go-live in a quieter month. A Friday-to-Monday go-live window with a Monday morning team on standby is the standard approach.
Upgrade paths supported
| From version | Upgrade complexity |
|---|---|
| Odoo 16 | Medium — 2 major versions, expect custom module rework |
| Odoo 17 | Low–medium — 1 major version, most standard modules carry forward cleanly |
| Odoo 15 or earlier | High — recommend a fresh implementation rather than a direct upgrade |
| Community Edition → Enterprise | Varies — data migration is possible but feature mapping requires planning |
Should you upgrade to Odoo 18 or move to Odoo 19?
Odoo 18 is the current LTS (Long Term Support) release, supported with security patches and bug fixes for 3 years. Odoo 19 is in development and expected for late 2025, but it will not carry LTS status immediately.
For production business systems, the LTS release is always the right choice. Upgrading to Odoo 18 now puts you on a stable, supported platform. You can re-evaluate Odoo 19 once it reaches LTS maturity.
What KometCode handles in an upgrade engagement
Our Odoo 18 upgrade engagements cover:
- Technical audit — review all custom modules, integrations, and data quality issues
- Test environment upgrade — run the upgrade on a copy of your production database and fix issues iteratively
- Custom module rebuild — update or rewrite custom code for Odoo 18 compatibility
- Integration testing — verify all third-party connections work post-upgrade
- UAT support — user acceptance testing with your team in the test environment
- Production go-live — scheduled migration with cutover plan and rollback procedure
- Post-go-live support — 2–4 weeks of dedicated support to handle day-one issues
For businesses with more complex customisation — particularly manufacturing companies running MRP, PLM, or shop floor modules — we recommend starting the audit 6–8 weeks before your planned go-live.
Getting started
If you are running Odoo 16, 17, or an older version and want to understand what an Odoo 18 upgrade would involve for your specific setup, contact KometCode for an assessment. We will review your current configuration and give you a realistic scope and timeline before any commitment is made.
We implement and upgrade Odoo 18 and Odoo 19 for clients in Ahmedabad, Gujarat, across North America, and globally on remote engagements.
