Ant Design Migration Guide

Migrate Ant Design projects between major versions, primarily v4 to v5.

When to Use

• Upgrading from antd v4 to v5
• Addressing deprecated component APIs
• Replacing removed components or features
• Converting from Less to CSS-in-JS styling

Instructions

1. Review the migration guide at https://ant.design/docs/react/migration-v5
2. Key migration steps from v4 to v5:
   • Replace less theme customization with ConfigProvider theme tokens
   • Update removed components: BackTop → FloatButton.BackTop, Comment → use @ant-design/compatible
   • Replace message.useMessage(), notification.useNotification(), modal.useModal() hooks
   • Update deprecated props (check migration guide for full list)
3. Use the @ant-design/codemod-v5 tool for automated migrations
4. For the complete breaking changes list, fetch https://ant.design/llms-full.txt

Notes

• Ant Design v5 drops Less in favor of CSS-in-JS
• Class name prefixes changed; if you used ant- prefix class names, update to dynamic class names
• Some component APIs have changed; check the migration guide for each component
