Does anyone has good documentation/examples about state migration? Let's imagine that I have a class in the state and want to add one field. I'm not using avro or anything like that. What are my option to make it happen? I've been reading the documentation but it's a little bit confusing to me. I know i could use

TypeInfoFactory

and

@TypeInfo

but I have no idea how to implement a

TypeInformation

class. I've also seen videos where they say that the serializer goes to memory with the object being serialized, how can i create a map function between the 2 version of my class? To me this is a common use case but I can't find any good resources clearly explaining how address this issue.
