Migrating PlantUML from Confluence Data Center to Confluence Cloud
If you’ve been using PlantUML for Confluence on Confluence Data Center, you already know how powerful it is for creating architecture diagrams, sequence flows, and other technical visuals directly in your wiki. But with Atlassian moving full steam ahead on Cloud, many teams are stuck wondering:
> “What happens to all our PlantUML macros when we migrate to Confluence Cloud?”
Here’s the bad news: Confluence Cloud doesn’t support server-side rendering of PlantUML macros natively. Many apps you’ve relied on in Data Center are either unavailable or work differently in Cloud — and manually converting hundreds (or thousands) of macros just isn’t realistic.
Meet the PlantUML Migration Tool - from Capable
We built a tool to fix this. Our PlantUML Migration Tool automates the process of migrating your PlantUML content from Data Center to Confluence Cloud, converting diagrams into a modern, cloud-native format that works seamlessly with your existing pages.
No more broken macros. No more scrambling to recreate diagrams. Just a clean, automated migration with minimal disruption.
🔧 How It Works
- Scan: The tool scans your Confluence spaces and identifies all PlantUML macros.
- Convert: Each macro is translated into a cloud-compatible diagram block, using SVG previews, Markdown, or a supported diagramming tool.
- Preserve: We maintain version history and page structure, so nothing gets lost in translation.
- Verify: You’ll get a report of every page touched, so you can audit before going live.
Whether you’re doing a one-time lift-and-shift or planning a phased rollout, the tool fits right into your migration workflow.
✅ Why This Matters
- Save time: Skip the manual copy-paste and error-prone rewrites.
- Reduce risk: Know exactly what’s being converted and how.
- Cloud-ready: Future-proof your content for Atlassian’s cloud-first roadmap.
- No surprises: Full control over which diagrams are migrated and how.
If you’re an admin, IT lead, or Atlassian partner running enterprise migrations, this tool is a game-changer.
🚀 Available Now
We’re excited to launch the PlantUML Migration Tool for Confluence Cloud, available today. If you’re migrating from Data Center, we’d love to help you streamline the process.
