Odoo upgrade decision guide
Odoo 17 left standard support in September 2026. Odoo's subscription agreement adds a yearly fee of 25% for databases on versions older than the three most recent. Estimate it with your own figures, then choose: upgrade, pay for a period, or reassess the platform.
Direct answer
For Odoo 17 Enterprise customers, the choice is between the cost of an upgrade project and the cost of the fee plus the risk of running without security updates. The estimator below compares the first two with your own figures.
The fee terms come from Odoo's current agreement. Older signed agreements may differ, and this page is not legal advice.
The clause and the dates
"Once per year, and no earlier than 6 months after the release of a new major version of the Software, if the Customer's database is on a version older than the Covered Versions, the Customer agrees to pay an extra fee equal to 25% of the annualized price, calculated based on the Customer's current per-user price and number of Users and Light Users."

Already older than the three covered versions. Check your agreement and invoices to see whether the fee already applies.
Odoo offers extended support for an additional fee on these hosting types only, and on Odoo.sh only for limited versions.
Extended support is not available. Odoo's upgrade documentation warns that an automatic upgrade starts if no action is taken before the due date.
Readiness check
Mark each area that applies to your database.
Do you run custom or third-party modules?
Odoo's upgrade documentation says a database with custom modules cannot be upgraded until those modules are available for the target version.
Have you built fields, screens or automations in Studio?
List each one and test it in an upgraded test database. Odoo's pricing page places Studio in the Custom plan.
Do other systems read or write Odoo data?
Retest each integration on the target version. Odoo 19 added the external JSON-2 API, and Odoo 20 adds a connection through MCP.
Do you rely on custom finance reports, bank rules or payment status filters?
Odoo 20 renames payment statuses and adds a bank consistency rule. Test month-end steps before you switch.
Is your database large or many years old?
Rehearse the upgrade on a full copy and check performance and data before you plan the cutover.

Fewer known complications. Still request an upgraded test database and test your main processes.
FAQ
Odoo's support policy lists the end of standard support for Odoo 17.0 as September 2026. Security updates are only provided during standard support.
Section 5.1 of Odoo's Enterprise Subscription Agreement says that once per year, and no earlier than six months after a new major release, a database on a version older than the three most recent major versions pays an extra fee equal to 25% of the annualized price.
Odoo 20 was released on September 24, 2026, which makes Odoo 17 older than the covered versions. Our estimate is that the fee could apply from about March 24, 2027, depending on your billing cycle. Check your own agreement and invoices; older signed agreements may differ.
Yes. The clause bases the fee on your current per-user price and your number of Users and Light Users.
Odoo says you can upgrade to any major version still under standard support, or one that left standard support less than six months ago. Today that means Odoo 18 (support until September 2027, planned), Odoo 19 (September 2028, planned) or Odoo 20 (September 2029, planned).
Odoo offers extended support for an additional fee, only on Odoo.sh for limited versions and on-premise. It is not available on Odoo Online.
Odoo's pricing page says upgrades are included in all plans at no extra fee. Maintenance of custom code and implementation services are not included, so porting custom modules and testing still cost time or money.
OPS is an Odoo partner and a NetSuite partner, and earns fees from upgrade and implementation work. We may recommend upgrading, paying the fee for a period, or reassessing the platform, depending on your situation.
