# Gamma Migration Deep Dive ## Current State !`npm list 2>/dev/null | head -10` ## Overview Migrate presentation workflows from PowerPoint, Google Slides, Canva, or other platforms to Gamma's AI-powered generation. Gamma takes a fundamentally different approach -- instead of manually placing slides, you provide content and Gamma generates the presentation. Migration is about converting your content pipeline, not your slide files. ## Prerequisites - Gamma API access (Pro+ plan) - Source presentations accessible for content extraction - Node.js 18+ for migration scripts - Completed `gamma-install-auth` setup ## Migration Approaches | Approach | When to Use | Effort | |----------|-------------|--------| | Content extraction + regeneration | Lots of text-heavy presentations | Medium | | Import via Gamma UI | One-off migration of key decks | Low | | Template recreation | Repeatable presentation formats | Medium | | Parallel operation | Gradual transition over time | Low | **Key insight:** You don't "import" slides into Gamma.
