**Tab Group & Tab Macros in Migrated Pages**

- After migrating from DC to Cloud, *tab groups* and *tab macros* appear as flattened structures in the UI on page launch.

- To view the content properly, the editor needs to be converted. In most Confluence versions, a **Convert Page** button will be displayed when you click **Edit**.

**Conversion Process**

- Clicking **Convert Page** reveals the tab group and tab data.
- Once updated, the page displays the legacy *tab-group* and *tabs* macros correctly in the new environment.

**External Links Behavior**

- External links will open in a new tab when clicked.
- The Forge platform shows a security warning before redirecting. Users must acknowledge this warning to proceed.

**Macro Nesting Limitation**

- The new editor does **not support macro nesting** (i.e., placing one macro inside another) except confluence macros.
- Because of this limitation, additional macros cannot be embedded within the new Forge app.
- The listed macros in the below page are not supported in cloud platform.
