 [//]: # (title: Migrate to the new memory manager)

 This guide compares the new [Kotlin/Native memory manager](native-memory-manager.md) with the legacy one and
 describes how to migrate your projects.

-## Support both new and legacy memory managers
-
-If you're a library author and need to maintain support for the legacy memory manager or want to have a fallback in case of
-issues with the new memory manager, you can temporarily support code for both new and legacy memory managers.
-
-To ignore deprecation warnings, do one of the following:
-
-* Annotate usages of the deprecated API with `@OptIn(FreezingIsDeprecated::class)`.
-* Apply `languageSettings.optIn("kotlin.native.FreezingIsDeprecated")` to all the Kotlin source sets in Gradle.
-* Pass the compiler flag `-opt-in=kotlin.native.FreezingIsDeprecated`.
-
-See [Opt-in requirements](opt-in-requirements.md) for more details.
