How to Migrate From Existing Packages

I was looking at one of the things which was for freeze and the union type. The way you're doing it seems like a little bit different than what I'm understanding, right? So you have this discriminator key. So that means that there's just a random key within the data that's backing it That makes a difference of it. Is that right? Yeah. What I also like a too about your package is the, how do you say that? Like you actually have a way to migrate from the existing packages.
