Handles XML views, Python API changes, JavaScript/OWL components, theme SCSS variables, manifest updates, security implementations, and database migrations. Use when user asks to upgrade Odoo modules, fix version compatibility issues, migrate themes between versions, or resolve Odoo 17/18/19 migration errors. Specializes in frontend RPC service migrations, view XML transformations, theme variable restructuring, and portal template XPath fixes. <example> Context: User wants to upgrade an Odoo module to a newer version user: "Upgrade my Odoo 16 module to Odoo 17" assistant: "I will use the odoo-upgrade skill to analyze your module, apply XML view transformations, update Python API decorators, and fix manifest version strings for Odoo 17 compatibility." <commentary>Core trigger - version migration request with module in scope.</commentary> </example> <example> Context: User hits migration errors after an Odoo version change user: "My module breaks with tree views in Odoo 19 - how do I fix it?" assistant: "I will use the odoo-upgrade skill to convert all tree views to list views, update attrs expressions to inline invisible, and fix any other Odoo 19 breaking changes." <commentary>Error-driven trigger - fix specific migration breakage.</commentary> </example> <example> Context: User needs data migration scripts user: "Generate migration scripts for upgrading my module from Odoo 17 to 19" assistant: "I will create pre-migrate.py and post-migrate.py scripts handling field renames, data transformations, and cleanup." <commentary>Data migration trigger - generates migration script templates.</commentary> </example>

Odoo Upgrade Assistant v5.0

When to Use

Activate when:

• Upgrading Odoo modules between versions (14-19)
• Fixing version compatibility errors
• Migrating themes or custom modules
• Resolving RPC service errors in frontend
• Converting XML views (tree->list, search groups)
• Updating SCSS variables for Odoo 18/19 themes
• Fixing portal view XPath inheritance errors
• Migrating JavaScript from OWL v1 to v2

Upgrade Workflow

1. Analyze - Read __manifest__.py, identify source version, scan all files
2. Backup - Create timestamped backup before changes
3. Pre-check - Run scripts/cli.py precheck <path> --target <version> to identify all issues
4. Transform - Apply transforms in order: manifest, XML, Python, JS, SCSS
5. Validate - Run scripts/cli.py validate <path> to check syntax
6. Test - Install module: python -m odoo -d DB -i MODULE --stop-after-init

XML/View Transformations

Tree to List (Odoo 19)

<!-- Tags -->        <tree> -> <list>,  </tree> -> </list>
<!-- view_mode -->   tree,form -> list,form
<!-- XPath -->       //tree -> //list
<!-- Remove -->      edit="1" attribute

Search Views (Odoo 19)

Remove <group> tags - place filters at root level. Add <separator/> before group_by filters.

Kanban Templates (Odoo 19)

t-name="kanban-box" -> t-name="card". Remove js_class="crm_kanban".

Cron Jobs (Odoo 19)

Remove <field name="numbercall"> - field no longer exists.

Form View Context (Odoo 19)

active_id -> id in context expressions.

Snippet Options (Odoo 19)

Remove templates inheriting website.snippet_options - system redesigned.

Attrs to Inline (Odoo 18/19)

attrs="{'invisible': [('state','=','draft')]}" -> invisible="state == 'draft'"

Python API Migrations

Slug/Unslug (Odoo 18+)

# Old: from odoo.addons.http_routing.models.ir_http import slug
# New: use request.env['ir.http']._slug(value)

URL For (Odoo 19)

# Old: from odoo.addons.http_routing.models.ir_http import url_for
# New: self.env['ir.http']._url_for('/path')

Controller Type (Odoo 19)

type='json' -> type='jsonrpc' in @http.route decorators.

View Mode (Odoo 19)

'view_mode': 'tree' -> 'view_mode': 'list' in Python dicts.

JavaScript/OWL Migrations

RPC Service (Odoo 19)

RPC service is NOT available in frontend/public components. Replace useService("rpc") with a _jsonRpc helper method using the fetch API with CSRF token handling.

OWL Lifecycle Hooks (Odoo 18+)

OWL 1.x (Odoo 14-17)	OWL 2.0 (Odoo 18+)
constructor(parent, props)	setup()
willStart()	onWillStart(callback)
mounted()	onMounted(callback)
patched()	onPatched(callback)
willUnmount()	onWillUnmount(callback)
willUpdateProps()	onWillUpdateProps(callback)

Theme SCSS Variables (Odoo 19)

Use $o-theme-* prefixed variables instead of bare Bootstrap names:

• $headings-font-weight -> $o-theme-headings-font-weight
• $font-size-base -> $o-theme-font-size-base

Color palettes must include 'menu', 'footer', 'copyright' assignments:

$o-color-palettes: map-merge($o-color-palettes, (
    'my_theme': (
        'o-color-1': #124F81,
        'menu': 1,
        'footer': 4,
        'copyright': 5,
    ),
));

Portal View XPath Migration (Odoo 19)

Sale portal templates restructured with named selectors:

Headers: th[@id='product_qty_header'], th[@id='product_unit_price_header'], th[@id='product_discount_header'], th[@id='taxes_header'], th[@id='subtotal_header']

Body: tr[@name='tr_product'], td[@name='td_product_name'], td[@name='td_product_quantity'], td[@name='td_product_priceunit'], td[@name='td_product_discount'], td[@name='td_product_taxes'], td[@name='td_product_subtotal']

Mail Template Migration (Odoo 19)

Remove env parameter from format helpers:

<!-- Old --> format_datetime(env, object.date_start)
<!-- New --> format_datetime(object.date_start)

XML entity encoding - use numeric references: © -> ©,   ->  , — -> —

Bootstrap 4 to 5 Class Migration

Bootstrap 4	Bootstrap 5
ml-*/mr-*	ms-*/me-*
pl-*/pr-*	ps-*/pe-*
text-left/text-right	text-start/text-end
float-left/float-right	float-start/float-end
sr-only	visually-hidden
badge-primary	bg-primary
font-weight-bold	fw-bold
no-gutters	g-0

Data Migration Scripts

Place migration scripts under module/migrations/VERSION/:

• pre-migrate.py - Before ORM update (use raw SQL only)
• post-migrate.py - After ORM update (can use env/ORM)
• end-migrate.py - After all modules updated (cleanup)

Each must define def migrate(cr, version): and guard with if not version: return.

Common patterns:

Pattern	Pre-Migrate	Post-Migrate
Field rename	ALTER TABLE RENAME COLUMN	Update views
Selection to M2O	Backup values	Map to records
Add required field	Nothing	Populate defaults
Model rename	Rename table + ir_model_data	Update foreign keys

With openupgradelib: rename_fields(), rename_models(), rename_xmlids(), rename_columns(), logged_query().

Common Errors Quick Reference

Error	Cause	Fix
Service rpc not available	useService("rpc") in frontend	Replace with _jsonRpc helper
Invalid field numbercall	Field removed	Remove from cron XML
Invalid view definition (search)	<group> in search	Remove group tags
Missing card template	kanban-box renamed	Use t-name="card"
Cannot import slug	Import moved	Use compatibility wrapper
website.snippet_options not found	System redesigned	Remove the template
active_id not found	Context change	Replace with id
