So I have an old project that has landed on my door which has a load of Spine animations created in Version 2.1. This have been exported for use in Unity so I only have the exported skeleton JSON and the textures. Currently without getting the client to start hunting for the old animations created by an external agency I wanted to first check if there was a way to import them into the latest version of Spine so that I can re-export them so that I can use them with the latest Unity package.

Any help or advice would be really appreciated.
Thanks in advance.
