Legacy connectors will be deprecated on January 1, 2026
- Assess your workflow to see if you can migrate
- Download legacy installers you still need (available until Jan 1, 2026)
- Start your migration if your workflow is supported
What the deprecation means
After January 1, 2026:- Legacy connector installers and Speckle Manager will be removed from https://releases.speckle.systems/legacy-connectors
- Already installed legacy connectors will continue to work locally
- No active forum support will be provided
- Current connectors will no longer maintain backwards compatibility with legacy models
Assess your workflow
Before migrating, determine if your workflow is supported in V3 connectors.✅ Migrate to V3 now
These workflows have full support in V3 connectors:| Workflow | Migration status | Notes |
|---|---|---|
| SketchUp ↔ Revit | ✅ Full support | Migrate now |
| Blender (all workflows) | ✅ Full support | Migrate now |
| Power BI | ✅ Full support | Migrate now |
| Revit ↔ Rhino (direct shapes) | ✅ Supported | Use V3’s assign category feature (guide) |
| Revit → Revit (direct shapes) | ✅ Supported | Works with direct shapes only |
⏸️ Continue with legacy connectors

- Mac versions of Rhino and ArchiCAD require legacy connectors
- Download necessary installers before January 1, 2026 and save them securely
- Complete existing projects on your current timeline
- Avoid starting new projects with legacy connectors
- Contact your workspace administrator if you need custom migration assistance (paid workspaces only)
Migration steps
1
Remove legacy connectors
Uninstall old Speckle plugin files from your authoring tool or remove them via your plugin manager.
2
Install V3 connectors
Visit the V3 connectors page for downloads and installation instructions.
3
Create workspace projects
V3 connectors require workspace-based projects.
- Navigate to your workspace in the Speckle web interface
- Create a new project for each workflow you want to upgrade
4
Send your data
Because legacy and V3 connectors use different data models, you need to resend your models:
- Open your model in your authoring tool (for example, Revit, Rhino, SketchUp)
- Use the V3 connector to send your model to the newly created project
5
Test and verify
- Open the new project in the Speckle web interface to verify your data
- Update any scripts or automation tools to work with the new workspace project structure
- Test receiving workflows in destination applications to ensure compatibility

Why upgrade to V3
V3 connectors offer significant improvements:- Faster and more reliable performance
- Expanded property support and consistent schemas across connectors
- Workspace-based projects that enable true team collaboration
- Direct integration with Speckle Intelligence to turn design data into actionable project insights
