When to Use

Use this skill when the user asks to upgrade an existing C/C++ ovrtx application from 0.3.x to 0.4.x, where the same code must now feed the renderer through an attached ovstage instance. Typical prompts: "upgrade from 0.3 to 0.4 with ovstage", "ovrtx 0.4 ovstage 0.1 migration", "migrate my ovrtx app", "port my application to ovstage".
