What changes between Odoo 18 and Odoo 19 only: first what to change in custom modules, then the changes we flagged week by week. Tick them off as you go; ticks stay in this browser.
Coming from an older version? Do the earlier steps first.
13 breaking, 9 deprecated but still working in 19.0. Started from OCA's migration guides; we checked each one in the Odoo code.
The decorator no longer exists, so the module fails to import. RPC now returns recordsets as lists of ids by itself.

auto_join=True is ignored from 19.0 (only an "unknown parameter" warning), so searches through the field lose the behaviour without an error.

New databases no longer get demo data unless created with --with-demo, so tests that rely on env.ref() of demo records fail.
partner = self.env.ref('base.res_partner_2')partner = self.env['res.partner'].create({'name': 'Test partner'})Checked in: 18.0/odoo/tools/config.py:114, 19.0/odoo/tools/config.py:233
The ORM hooks odoo-test-helper relied on are gone. Register the model with odoo.orm.model_classes.add_to_registry, set it up, and clean it up after the class.
loader = FakeModelLoader(cls.env, cls.__module__)
loader.backup_registry()
loader.update_registry((FakeModel,))add_to_registry(cls.registry, FakeModel)
cls.registry._setup_models__(cls.env.cr, ['fake.model'])

On users, views, menus, actions, reports and website page properties the field is now group_ids, with no alias. Update Python, XML data, view arches and domains.
<field name="groups_id" eval="[(4, ref('base.group_user'))]"/>

res.groups lost its category_id. Create a res.groups.privilege record, which carries the module category, and set privilege_id on your groups.

kanban-box still renders in 18.0 with a console warning; 19.0 requires a card template and raises without one. Inside card, fields are plain <field> elements, no wrapping divs; kanban-tooltip is gone, and the color picker is <field name="color" widget="kanban_color_picker"/>.

Callers now pass domain= as a keyword, so an override that still names it args raises TypeError.

odoo.registry() logs a deprecation warning in 18.0. In 19.0 the odoo package no longer has it, so the import fails.

Search methods of computed fields no longer receive '=' or '!=': the domain optimizer turns them into 'in' and 'not in' with a set, e.g. ('flag', '=', True) arrives as 'in', {True}. Returning a list still works; returning a Domain is optional.
def _search_is_late(self, operator, value):
if operator == '=' and value:
return [('date_deadline', '<', fields.Date.today())]def _search_is_late(self, operator, value):

_sql_constraints is ignored from 19.0: only a warning is logged, and the constraint is silently not created. Declare each one as a class attribute; the database name is the table plus the attribute name.
_sql_constraints = [
('name_uniq', 'unique(name)', 'Name must be unique'),
]_name_uniq = models.Constraint('UNIQUE(name)', 'Name must be unique')
_partner_date_idx = models.Index('(partner_id, date)')Checked in: 19.0/odoo/orm/model_classes.py:162, 19.0/odoo/orm/table_objects.py:79 · Odoo: #175783
From 19.0 archiving no longer goes through toggle_active, so its overrides stop firing. Calls still work until 20.0, where the method is gone. action_archive and action_unarchive already exist in 18.0.

res = super().toggle_active()

odoo.osv warns in 19.0 and no longer exists in 20.0, so the import fails there. Build domains with Domain and its &, | and ~ operators, or Domain.AND and Domain.OR.
from odoo.osv import expression
domain = expression.AND([domain, [('state', '=', 'done')]])from odoo.fields import Domain

Domain values on date fields can be relative strings such as 'today -7d'. Optional: context_today() expressions still work.
[('date', '>=', (context_today() - relativedelta(days=7)).strftime('%Y-%m-%d'))][('date', '>=', 'today -7d')]Checked in: 19.0/odoo/tools/date_utils.py:116, 19.0/odoo/orm/domains.py:1554 · Odoo: #216665
self._cr, self._uid and self._context still work in 20.0 but log a deprecation warning. Replace them now; it is a safe search and replace.
self._cr.execute(query)
lang = self._context.get('lang')self.env.cr.execute(query)
lang = self.env.context.get('lang')Checked in: 19.0/odoo/orm/models.py:5931, 20.0/odoo/orm/models.py:5395
self.env.tz gives the user or context timezone. In 19.0 it is a pytz timezone; in 20.0 it is a ZoneInfo and pytz is no longer an Odoo requirement, so .localize() and .normalize() calls break.
tz = pytz.timezone(self.env.context.get('tz') or self.env.user.tz or 'UTC')
local = pytz.utc.localize(dt).astimezone(tz)from datetime import UTC

type="json" is still mapped to jsonrpc in 20.0, with a deprecation warning. Switch when the module no longer has to run on 18.0.

ormcache_context warns in 19.0 and is gone in 20.0, where the import fails. Pass every context key as a self.env.context.get() expression.

read_group is deprecated in 19.0, and in 20.0 it has a new, final signature, so old calls and overrides break. Use _read_group in backend code and formatted_read_group for UI-shaped results.
res = Order.read_group([('state', '=', 'sale')], ['amount_total:sum'], ['partner_id'], lazy=False)for partner, total in Order._read_group([('state', '=', 'sale')], ['partner_id'], ['amount_total:sum']):

odoo.SUPERUSER_ID still works in 20.0 without a warning, but it is a shortcut meant to go now that odoo is a namespace package.

From the module lists of both branches. Community commits link to the change that removed the module; Enterprise code is private, so we only name its modules.
Custom modules or integrations need a change before or during the upgrade.
Depending on the PostgreSQL version, foreign key violations can be raised as RESTRICT violations. The ORM now treats both the same way, and custom code catching only ForeignKeyViolation should do the same.
Mentioned in: What's new in Odoo 20
Behaviour changes to check in testing. Usually nothing to change.
Warnings about unsupported domain values, such as NewId or records, and about upper-case operators now name the code that built the domain. Run your test suite and outdated patterns in custom modules are easy to find.
Mentioned in: What's new in Odoo 20
Every upgrade_code script now runs in the test suite, so the scripts that rewrite custom code for new versions keep working. Use the '# test: false' and '# test: skip' markers for scripts that can't be tested this way.
Mentioned in: What's new in Odoo 20
On databases with glibc collations such as en_US.UTF-8, moving a node could leave its descendants with a stale parent_path. The range now uses COLLATE "C", and the parent_path index is rebuilt to match.
filtered_domain() computed quarters in four-month groups and counted weekdays from Monday, so it could disagree with search(). Both now follow PostgreSQL. Check custom code that relied on the old in-memory results.
