Breaking Changes by Hop
Click each hop to see the detailed changes your database will undergo.
| Severity | Table / Field | Change | Impact |
|---|---|---|---|
| CRITICAL | account_account | user_type_id (M2O) → account_type (selection) Type changed | Account type completely restructured from a related table to an inline selection. Requires French PCG mapping |
| CRITICAL | account_account_type | (full table) → (deleted) Table deleted | Entire account type table removed from the database |
| MEDIUM | product_template | product_uom → product_uom_id Renamed | Unit of measure field renamed for consistency |
| Severity | Table / Field | Change | Impact |
|---|---|---|---|
| HIGH | (Docker) | UID 101 → UID 100 Type changed | Odoo 18 Docker image changes UID from 101 to 100 — filestore permissions break silently |
No major breaking changes in this hop. Mostly incremental improvements and minor adjustments.

The account_account_type table is completely deleted. All account classification moves to a selection field on account_account. We map it automatically using French PCG codes (1xx = equity, 6xx = expense, 7xx = income, etc.).
Yes, as long as your database is under 2 GB and you're running native Odoo modules. This path does not cross the v15-v16 structural boundary, so it's more predictable.
We handle it. The v17-v18 hop changes the Odoo Docker UID from 101 to 100, which breaks filestore permissions. Our pipeline fixes this automatically.
