This skill helps agents migrate HeroUI v2 applications to v3. HeroUI v3 introduces breaking changes: compound components, no Provider, Tailwind v4, and removed hooks.
curl -fsSL https://heroui.com/install | bash -s heroui-migration
Do NOT assume v2 patterns work in v3. Always fetch migration guides before implementing changes.
| Feature | v2 (Migrate From) | v3 (Migrate To) |
|---|---|---|
| Provider | <HeroUIProvider> required | No Provider needed |
| Component API | Flat props: <Card title="x"> | Compound: <Card><Card.Header> |
| Event handlers | onClick | onPress |
| Styling | classNames prop | className prop |
| Hooks | useSwitch, useDisclosure, etc. | Compound components, useOverlayState |
| Packages | @heroui/system, @heroui/theme | @heroui/react, @heroui/styles |
For migration details, examples, and step-by-step guides, always fetch documentation:
# List all available component migration guides
node scripts/list_migration_guides.mjs
# Get main migration workflow (full or incremental)
node scripts/get_migration_guide.mjs full
node scripts/get_migration_guide.mjs incremental
# Get component-specific migration guides
node scripts/get_component_migration_guides.mjs button
node scripts/get_component_migration_guides.mjs button card modal
# Get styling migration guide
node scripts/get_styling_migration_guide.mjs
# Get hooks migration guide
node scripts/get_hooks_migration_guide.mjs

When using Cursor or other MCP clients, configure the Migration MCP server for tool-based access:
{
"mcpServers": {
"heroui-migration": {
"url": "https://migration-mcp.heroui.com"
}
}
}
Always fetch the agent guide before starting: node scripts/get_migration_guide.mjs full or incremental
