# Default system deployment versions
When installing or upgrading Elastic Cloud Enterprise, its associated system deployments run by default on the Elastic Stack versions listed in the following table.
Note that since version 2.7.0, system deployments are automatically upgraded when upgrading Elastic Cloud Enterprise. Don’t attempt to upgrade system deployments manually. Instead, follow the [ECE upgrade instructions](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4491/deploy-manage/upgrade/orchestrator/upgrade-cloud-enterprise).
