 ## Semantic Conventions
 
-This package uses `@opentelemetry/semantic-conventions` version `1.22+`, which implements Semantic Convention [Version 1.7.0](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.7.0/semantic_conventions/README.md)
+This instrumentation implements Semantic Conventions (semconv) v1.7.0. Since then, networking (in semconv v1.23.1) and database (in semconv v1.33.0) semantic conventions were stabilized. As of `@opentelemetry/[email protected]` support has been added for migrating to the stable semantic conventions using the `OTEL_SEMCONV_STABILITY_OPT_IN` environment variable as follows:
+
+1. Upgrade to the latest version of this instrumentation package.
+2. Set `OTEL_SEMCONV_STABILITY_OPT_IN=http/dup,database/dup` to emit both old and stable semantic conventions. (The `http` token is used to control the `net.*` attributes, the `database` token to control to `db.*` attributes.)
+3. Modify alerts, dashboards, metrics, and other processes in your Observability system to use the stable semantic conventions.
+4. Set `OTEL_SEMCONV_STABILITY_OPT_IN=http,database` to emit only the stable semantic conventions.
+
+By default, if `OTEL_SEMCONV_STABILITY_OPT_IN` includes neither of the above tokens, the old v1.7.0 semconv is used.
+The intent is to provide an approximate 6 month time window for users of this instrumentation to migrate to the new database and networking semconv, after which a new minor version will use the new semconv by default and drop support for the old semconv.
+See [the HTTP migration guide](https://opentelemetry.io/docs/specs/semconv/non-normative/http-migration/) and the [database migration guide](https://opentelemetry.io/docs/specs/semconv/non-normative/db-migration/) for details.
