The old class name is:

@Serializable
@SerialName("OldClass")
class OldClass(
    val member: String,
) : IClass {
...
}

Now I want to rename it to:

@Serializable
@SerialName("NewClass")
class NewClass(
    val member: String,
) : IClass {
...
}

The problem is, users might have already serialized and saved it. So, what I want is:

• When serializing, use the NewClass
• When deserializing, no matter if it reads OldClass or NewClass, always decode with NewClass

The SerializeModule that used for serializing/deserliazing looke like:

val serializeModule = SerializersModule {
    polymorphic(IClass::class) {
        subclass(OldClass::class) 
        subclass(NewClass::class)

        ...
    }
}

Currently, I need to implement both classes, which are exactly the same, is it possible to only implement the NewClass, and use an alias for the old one?
