Legacy: Godot 1.x / early 2 (archaeology)
Tier C — there is no official upgrading_to_godot tutorial for 1→2. Use release notes, the download archive, and GitHub releases. Oldest common docs host: Godot 2.1 docs.
Honesty gate
- Prefer rewrite on latest 3.x or library target (4.7+) for small projects.
- Large art/audio libraries: extract assets, rebuild scenes/scripts on modern Godot.
- NEVER claim automatic 1.x→4.x conversion.
Next hops
- If somehow on 2.x already → 2-to-3.md
- Stabilize on latest 3.x → ../bridges/3-to-4.md
- Then 4.x minor hops via ../hop-index.md
