+sidebar_label: "Deprecation: dbt Metrics and Legacy dbt Semantic Layer"

+---
+
+dbt Labs has deprecated dbt Metrics and the legacy dbt Semantic Layer, both supported on dbt version 1.5 or lower. This change starts on December 15th, 2023.
+
+This deprecation means dbt Metrics and the legacy Semantic Layer are no longer supported. We also removed the feature from the dbt Cloud user interface and documentation site.
+
+### Why this change?
+
+The [re-released dbt Semantic Layer](/docs/use-dbt-semantic-layer/dbt-sl), powered by MetricFlow, offers enhanced flexibility, performance, and user experience, marking a significant advancement for the dbt community.
+
+### Key changes and impact
+
+- **Deprecation date** — The legacy Semantic Layer and dbt Metrics will be officially deprecated on December 15th, 2023.
+- **Replacement** — [MetricFlow](/docs/build/build-metrics-intro) replaces dbt Metrics for defining semantic logic. The `dbt_metrics` package will no longer be supported post-deprecation.
+- **New feature** — Exports replaces the materializing data with `metrics.calculate` functionality and will be available in dbt Cloud in December or January.
+
+
+### Breaking changes and recommendations
+
+- For users on dbt version 1.6 and lower with dbt Metrics and Snowflake proxy:
+  - **Impact**: Post-deprecation, queries using the proxy _will not_ run.
+  - **Action required:** _Immediate_ migration is necessary. Refer to the [dbt Semantic Layer migration guide](/guides/sl-migration?step=1)
+
+- For users on dbt version 1.6 and lower using dbt Metrics without Snowflake proxy:
+  - **Impact**: No immediate disruption, but the package will not receive updates or support after deprecation
+  - **Recommendation**: Plan migration to the re-released Semantic Layer for compatibility with dbt version 1.6 and higher.
+
+### Engage and support
+
+- Feedback and community support — Engage and share feedback with the dbt Labs team and dbt Community slack using channels like [#dbt-cloud-semantic-layer](https://getdbt.slack.com/archives/C046L0VTVR6) and [#dbt-metricflow](https://getdbt.slack.com/archives/C02CCBBBR1D). Or reach out to your dbt Cloud account representative.
+- Resources for upgrading —Refer to some additional info and resources to help you upgrade your dbt version:
