 end-to-end encrypted vector storage with automatic dimension detection and index optimization.
 
+* Deprecated components:
+
+- `redpanda_migrator` input and output (renamed to `legacy_redpanda_migrator`)
+- `redpanda_migrator_offsets` input and output (renamed to `legacy_redpanda_migrator_offsets`)
+- `redpanda_migrator_bundle` input and output (these are part of the legacy migration architecture and internally depend on the deprecated `legacy_redpanda_migrator` and `legacy_redpanda_migrator_offsets` components)
+
+These components have been renamed from their previous versions (without the `legacy_` prefix) to preserve backward compatibility. The new `redpanda_migrator` components introduced in this release contain breaking changes. Existing configurations using the previous `redpanda_migrator` components should use these `legacy_` prefixed versions to maintain current functionality.
+
+Users should migrate from deprecated components to the new unified `redpanda_migrator` input/output pair. For detailed migration instructions, see xref:guides:migration/migrate-unified-redpanda-migrator.adoc[].
