# Overview

> Metoro documentation for self-managed deployments

Welcome to the docs for the latest version of Metoro's self-managed offering.

11.0.0 moves self-managed installations onto Metoro's new-generation telemetry storage engine. Fresh installs create only the new-generation ClickHouse tables (JSON-native attributes, retention-cohort partitioning) and serve every query from them, bringing the storage layout in line with Metoro Cloud:

* Substantially lower ClickHouse merge and storage overhead for high-cardinality attributes
* 10-100x performance gains on queries
* The same query surface as before: no dashboards, alerts or API calls need to change
* The same chart values API as 10.x: existing values files remain valid with no configuration changes (the only addition is the `newTelemetryTablesAcknowledged: true` fresh-install confirmation)
* All 10.x features, including [Guardian - AI SRE](/docs/ai-sre/overview), [Distributed Incremental Query Caching](/docs/concepts/incremental-cache), [PromQL](/docs/metrics/promql) metric queries, GPU monitoring and metric autoscraping

## Upgrades

<Warning>
  11.0.0 is for **fresh installations only**. The new-generation tables use a different storage layout, and telemetry stored by a 10.x hub is not readable by an 11.x installation without migration. If you run an existing 10.x hub, do not upgrade to 11.0.0: contact Metoro support for the migration path (migration tooling is arriving shortly). See [Upgrading from 10.x](/docs/on-premises/11.x/upgrades/upgrading-from-10-x).
</Warning>

New installations should follow the [installation guide](/docs/on-premises/11.x/installation/planning). Existing 10.x hubs should stay on the [10.x release line](/docs/on-premises/10.x/overview) until Metoro support has confirmed a migration plan for their installation.
