Switching from CustomPress to another CPT tool?

Hello there,

I’m handing off an old project to a new developer who does not have WPMU. The site is only using CustomPress and I was looking for any ways to transfer the content of the custom post types to a new plugin. I did find this post, but it is 5 years old and likely outdated: https://premium.wpmudev.org/forums/topic/ability-to-switch-from-custompress

Is there any way to export from CustomPress to another tool?
