Hi, when @ark created this topic (thank you!), Play/Play+ Updates and Upgrade Path didn’t exist yet. Now that Polyend staff created that topic about the upgrade path it is better to keep the questions and discussion there in one place.
I would move these posts there but the software doesn’t want me for some reason… Instead, I’ll mark this topic to be closed in a week (just in case anyone wants to wrap up a comment here). For new comments and questions, please use Play/Play+ Updates and Upgrade Path.
