我通过机器翻译看了你的帖子，很遗憾没有理解你问题的意图。你的意思是，你目前有用Spine 2.1.27创建的骨架数据，想把它升级到新的版本？
I read your post through machine translation and unfortunately did not understand the intent of your question. Do you mean that you currently have skeleton data created with Spine 2.1.27 and would like to upgrade it to a newer version?
