+# Admin central
+
+Admin central is where instance administrators review Appsmith communications about upcoming release changes. It shows which of those changes apply to your instance, and whether any need action before you upgrade.
+
+The page is informational. It does not save configuration, and it does not change how the instance runs.
+
+Only users with Instance Administrator privileges can open Admin central. The page appears under **Instance** on self-hosted instances. It is not shown on Appsmith Cloud or on deployments where multiple organizations are enabled.
+
+## Open Admin central
+
+1. Sign in as an instance administrator.
+2. Open **Admin Settings**.
+3. Under **Instance**, select **Admin central**.

+
+Appsmith adds a notice when a change in an upcoming or current release requires administrator attention. Each notice can include:
+
+- A title and short description of the change
+- A severity indicator so you can tell informational updates from items that need action
+- Summary details, such as counts or status for the current instance
+- An expandable list of affected items when more context is available
+- A **Learn more** link to the documentation for that change
+
+If a notice says you must finish work on this instance before you upgrade, follow that notice’s documentation first. For workflow notices, see [Native workflow engine](/workflows/how-to-guides/native-workflow-engine).
+
+## When no action is required
+
+If there is nothing that needs attention, Admin central shows:
+
+> There is no action required for this instance.
+
+This is the expected state when no release communications apply to the instance. Notices appear when a change needs attention and disappear when that work is complete.
+
+## If the page does not load
+
+If Appsmith cannot load instance information, refresh the page and try again. You must stay signed in as an instance administrator.

+
+Before v2.3, Appsmith used **Temporal** to run workflows. Starting in **v2.3**, Appsmith is rolling out a **native workflow engine** to Enterprise customers. Appsmith enables the native engine on your instance. You do not need to turn anything on.
+
+The native engine runs as part of Appsmith. You continue to use the same workflow editor, triggers, run history, and approvals.
+
+## What happens when the native engine is enabled
+
+- **New workflow runs** use the native engine.
+- **Runs that already started**, including those waiting for approval, continue on Temporal until they finish.
+- **Schedules** continue to trigger as usual. You do not need to recreate them.
+- **Run history** still shows all runs in one place.
+
+You do not need to change your workflow code or the way you trigger workflows.
+
+## Check remaining Temporal approval runs
+
+If a workflow run that started on Temporal is waiting for approval, that run must finish or be stopped on Temporal.
+
+To see how many of those runs are still open:
+
+1. Open **Admin Settings**.
+2. Under **Instance**, select **Admin central**.
+
+Admin central lists remaining Temporal approval runs and the workflows they belong to. If there are none, no action is required.
+
+For more about the page, see [Admin central](/getting-started/setup/instance-configuration/admin-central).
+
+:::note
+Whenever possible, let open approval runs complete normally. Terminate a run only if you intend to stop that work.
+:::
+
+## What you should do
+
+Most teams do not need to change anything after Appsmith enables the native engine.
+
+If you use approval workflows, a later Appsmith release will remove Temporal. Wait until Admin central shows no remaining Temporal approval runs before you upgrade to that release.
