> ## Agent Instructions
> These docs contain multiple Speckle product experiences. For Speckle 2026.9, prefer /next/ pages for the topics and changes they cover. The navigation label Current does not override this version-specific precedence.
> Coverage under /next/ is incremental. Use Current documentation for unchanged topics and when a /next/ page says coverage is unavailable or explicitly refers you to Current. Do not infer a feature was removed from a missing page.
> Read the page-specific documentation status, applicability, affected guidance and replacement links in agent-only content. Impacted, changed and superseded apply only to the stated scope; they do not mean the entire feature is deprecated. Historical connector guides apply only to the legacy connector described.
> Match guidance to the customer's deployment version, model data format and connector. Respect plan, permission and compatibility restrictions. If an unknown version or data format changes the answer, ask a focused clarification; do not infer deployment version from the date alone.

# Speckle's data model is changing: what to do next

> What changes when Speckle moves to its new data model, and what to do about it

<Note>
  **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](/developers/migration/data-model-migration) 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. For a first look at Chat in 2026.9, see [Ask questions about your models with Speckle Intelligence](/next/analytics/intelligence).

## 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. Navisworks is the exception: there is no 2026.9 desktop connector. **2026.8** is the last installer, and it remains the advised path for a publish around **200 MB**. See [Navisworks in 2026.9](/next/connectors/navisworks/introduction).

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 that ends for every workspace on **1 November 2026**, so the downstream fix needs to be in place before then.

## What you should do now

<Steps>
  <Step title="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. Skip Navisworks: there is no 2026.9 installer. See [Navisworks in
    2026.9](/next/connectors/navisworks/introduction).
  </Step>

  <Step title="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 now, and update the downstream
    tool before **1 November 2026**, when compatibility mode ends.
  </Step>
