How does this skill assist with UI migration?

The skill provides a high-level migration strategy and timeline, helping you understand the trade-offs and structural changes required when moving to UI Toolkit.

Is UGUI still recommended for modern Unity games?

Yes, UGUI remains the preferred choice for 3D world-space UI, legacy project maintenance, and teams with deep existing expertise in GameObject-based UI.

Can I use UI Toolkit for runtime UI in older Unity versions?

UI Toolkit for runtime use is only considered production-ready for Unity 2021.3 LTS and later; earlier versions have experimental or no support.

When should I choose UI Toolkit over UGUI?

Use UI Toolkit for Unity 2021.2+ projects, complex data-driven UIs, and custom Editor tools to benefit from better performance and CSS-like styling.
