This page is for Speckle users and workspace admins/managers. If you build directly on Speckle
— SDKs, APIs, or Automate — see Data model migration for
developers instead.

What’s changing
Speckle is moving to a new data model that lets it handle much larger projects, and lets it work faster once you’re on it. Under the hood, your models get organized in a way that’s built for scale, and that also makes newer features — including Speckle Intelligence — able to understand how parts of your model relate to each other, not just what each part is.What isn’t changing
How you work day to day stays the same. Publish and load through your connectors, view and share in the web app, exactly as you do now — just faster once your project has migrated.Why we’re doing it
Bigger projects were starting to slow the old format down. The new one is built to hold much larger models without that penalty, and it opens the door to querying and understanding your data in ways the old format couldn’t support — including how Speckle Intelligence works out what connects to what.Who should pay closer attention
Most people don’t need to do anything. If you publish and load through Speckle’s desktop or web connectors, your workflow carries on unchanged. The one group worth flagging: if you rely on ACC sync or drag-and-drop uploads, and something downstream of Speckle — a script, a custom report, another tool — depends on the old data format, that connection could break after the migration. If that happens, ask us to switch your workspace into compatibility mode, which keeps things running in the old format while you sort out the downstream fix. Compatibility mode is a temporary bridge — it’s available until 1 November 2026.What you should do now
1
Update your connectors
Update from 1 September 2026, no later than 1 November 2026. Your existing connectors
keep working either way — updating just gets you the performance improvements sooner and avoids
any last-minute scramble.
2
Flag it if you rely on ACC sync or drag-and-drop
If you use ACC sync or drag-and-drop uploads and something downstream depends on the old data
format, ask us to switch your workspace into compatibility mode before 1 November 2026.
