-% What needs to be done: Refine
+Installing ECE on hosts without internet access is commonly referred to as an *offline* or *air-gapped* installation. ECE supports two air-gapped installation methods, depending on whether a private Docker registry is available. In both cases, you must download multiple Docker images and the installation script from Elastic, and load them onto your hosts or private registry.

+::::{note}
+    The versioning of {{es}} and {{kib}} is synchronized and versions where the major, minor, and patch levels match can be used together. Differences in build versions indicated by a dash do not affect compatibility.

+Before you start, you must:
 
-% Use migrated content from existing pages that map to this page:
+* Follow the same prerequisites described in [](./install.md#ece-install-prerequisites). This includes [](./identify-deployment-scenario.md) and [](./prepare-environment.md) steps.
+* [Configure your operating system](./configure-operating-system.md) in all ECE hosts.
+* Be part of the `docker` group to run the installation script. You should not install Elastic Cloud Enterprise as the `root` user.
+* Set up and run a local copy of the Elastic Package Repository, otherwise your deployments with APM server and Elastic agent won’t work. Refer to the [Running EPR in air-gapped environments](asciidocalypse://docs/docs-content/docs/reference/ingestion-tools/fleet/air-gapped.md#air-gapped-diy-epr) documentation.

 # Updating custom templates to support node_roles and autoscaling [ce-add-support-for-node-roles-and-autoscaling]
 
-Custom deployment templates should be updated in order to take advantage of new Elastic Cloud Enterprise features, such as [Data tiers](../../../manage-data/lifecycle/data-tiers.md) (that is, the new cold and frozen data tiers) and [Deployment autoscaling](../../autoscaling.md). By updating these templates we also ensure forward compatibility with future Elastic Cloud Enterprise versions that will require certain fields such as `node_roles` and `id` to be present in the deployment configuration.
-
-System owned deployment templates have already been updated to support both data tiers with `node_roles` and autoscaling. However, the custom templates that you created need to be manually updated by following the steps in this guide.
