How to Migrate from Monix to ZIO?

Monix's Task[A] can be easily replaced with ZIO's Task[A] (an alias for ZIO[Any, Throwable, A]). Translation should be relatively straightforward. Below, you'll find tables showing the ZIO equivalents of monix.eval.Task's methods.

Once you've completed the initial translation, you'll find that ZIO is outfitted with many additional methods which have no Monix equivalents, so have fun exploring the API and see if you can rewrite some of your logic at a higher level of abstraction, with more powerful combinators and fewer lines code.

If you are using operators from Cats Effect extension methods see also here.
