Overview
Comprehensive guide for migrating presentations and workflows from PowerPoint, Google Slides, Canva, and other platforms to Gamma with validation and rollback support.
Prerequisites
- Gamma API access
- Source platform export capabilities
- Node.js 18+ for migration scripts
- Sufficient Gamma storage quota
Instructions
Step 1: Inventory Source Presentations
Scan source directories for .pptx, .pdf, and .key files. Generate a JSON inventory with metadata (title, size, source platform, last modified).
Step 2: Build Migration Engine
Create a migration engine with concurrent batch processing, retry logic, and progress reporting. Use PQueue for concurrency control.
Step 3: Handle Platform-Specific Exports
- Google Slides: Export via Drive API as
.pptx, then import to Gamma - PowerPoint: Extract metadata from
docProps/core.xmlbefore import - Canva/Keynote: Export as
.pptxfirst, then import
Step 4: Validate Migrated Presentations
Verify each migrated presentation has slides, all assets loaded, and can export.
Step 5: Create Rollback Snapshots
Save source-to-Gamma ID mappings as snapshots. If migration fails, delete Gamma copies.
See detailed implementation for advanced patterns.
Output
- Migration inventory JSON
- Batch migration with concurrency control
- Platform-specific import handlers
- Validation and rollback support
Error Handling
| Issue | Cause | Solution |
|---|---|---|
| Import timeout | Large file size | Increase timeout to 120s |
| Asset missing | Embedded fonts/media | Re-export with embedded assets |
| Format mismatch | Unsupported features | Export as PDF fallback |
Examples
Supported Migration Paths
| Source | Format | Fidelity | Notes |
|---|---|---|---|
| PowerPoint | .pptx | High | Native import |
| Google Slides | .pptx export | High | Export first |
| Canva | .pdf/.pptx | Medium | Limited animations |
| Keynote | .pptx export | High | Export first |
| Markdown | .md | High | Structure preserved |
Migration Checklist
- Inventory all source presentations
- Test import with sample files
- Run migration in batches
- Validate each batch
- Update links and references

Expert guidance for Next.js Cache Components and Partial Prerendering (PPR). **PROACTIVE ACTIVATION**: Use this skill automatically when working in Next.js projects that have `cacheComponents: true` in their next.config.ts/next.config.js. When this config is detected, proactively apply Cache Components patterns and best practices to all React Server Component implementations. **DETECTION**: At the start of a session in a Next.js project, check for `cacheComponents: true` in next.config. If enabled, this skill's patterns should guide all component authoring, data fetching, and caching decisions. **USE CASES**: Implementing 'use cache' directive, configuring cache lifetimes with cacheLife(), tagging cached data with cacheTag(), invalidating caches with updateTag()/revalidateTag(), optimizing static vs dynamic content boundaries, debugging cache issues, and reviewing Cache Component implementations.
