+::::{admonition} Spaces support for integration assets
 
-{{agent}} integration assets can be installed only on a single {{kib}} [space](/deploy-manage/manage-spaces.md). If you want to access assets in a different space, you can [copy them](/explore-analyze/find-and-organize/saved-objects.md#managing-saved-objects-copy-to-space). However, many integrations include markdown panels with dynamically generated links to other dashboards. When assets are copied between spaces, these links may not behave as expected and can result in a 404 `Dashboard not found` error. Refer to known issue [#175072](https://github.com/elastic/kibana/issues/175072) for details.

-These limitations and future plans for {{fleet}}'s integrations support in multi-space environments are currently being discussed in [#175831](https://github.com/elastic/kibana/issues/175831). Feedback is very welcome. For now, we recommend reviewing the specific integration documentation for any space-related considerations.
+* {applies_to}`stack: ga 9.1` Fleet uses a space-aware data model for {{agent}} policies and integrations. Agent policies can now span multiple spaces, while integration assets remain space-specific. 
+
+  Integration assets are still installed per space, but can be managed and reinstalled independently in each space.
+
+  If you upgraded from an earlier version, enable space awareness in Fleet before managing integrations across spaces.

+* {applies_to}`stack: ga 9.0` In versions earlier than {{stack}} 9.1, integration assets can be installed in only one {{kib}} space. You can manually [copy them](/explore-analyze/find-and-organize/saved-objects.md#managing-saved-objects-copy-to-space) to other spaces. However, many integrations include markdown panels with dynamically generated links to other dashboards. When copied between spaces, these links might not behave as expected and can result in a `Dashboard not found` (404) error.
