Odoo 18, released in October 2024, tightened what Odoo 17 started: faster views, cleaner navigation, more eCommerce and accounting features, and further sales, CRM, project and HR work. Both versions are still in standard support, but not for equal lengths of time — Odoo's support table lists Odoo 17's standard support as ending in September 2026 and Odoo 18's in September 2027. So for anyone on Odoo 17 today, the decision is less whether to take 18 than whether to make one move to Odoo 19, which is supported to September 2028.

Questions we get asked
How long are Odoo 17 and Odoo 18 supported?
Odoo supports each major version for three years with helpdesk, bug fixing and security updates. Odoo 17, released in November 2023, is listed as ending standard support in September 2026; Odoo 18, released in October 2024, runs to September 2027; Odoo 19 to September 2028. After that a version moves to paid extended support on Odoo.sh and on-premise, without security updates.
Should I upgrade from Odoo 17 to Odoo 18, or straight to Odoo 19?
Straight to Odoo 19, in most cases. Odoo accepts an upgrade from any version onto any supported target, so 17 to 19 is one request rather than two. The porting and user-testing effort is broadly the same, and landing on Odoo 19 buys standard support until September 2028 instead of September 2027. Going to 18 makes sense mainly if a module you depend on has no Odoo 19 version.
Will my Odoo 17 customisations survive an upgrade?
Studio customisations and standard configuration are converted by Odoo's upgrade service for Enterprise subscribers. Custom Python modules, third-party apps and bespoke reports are not: their maintainers must publish a version for the target release before the upgrade can complete. External integrations need retesting too, since Odoo 19 introduced a JSON-2 API and deprecated XML-RPC and JSON-RPC.
What do Odoo 17 users notice first on Odoo 18?
Speed and navigation rather than new concepts. Odoo 18 kept Odoo 17's interface direction and refined list and form performance, search, and the eCommerce and accounting screens, so retraining is lighter than a 16 to 17 move. The safest way to find the real differences for your team is an upgraded test copy that each app's users work through before go-live.
What happens if I stay on Odoo 17 past September 2026?
The database keeps running, but the safety net changes. Standard support ends, so no more security updates; extended support on Odoo.sh and on-premise is available at a mandatory extra fee and covers helpdesk and bug fixes only, and Odoo Online does not offer it. Odoo also upgrades only onto supported versions, so the move gets larger the longer it waits.
