Copy Chatter feed from one object to another (of other SObject Type)

I need to migrate data from one object type to another. Including their Chatter feeds. First task is simple, but the second?

How would I best approach this? Are there AppExchnage tools for that or existing Apex code? What would I have to think of?

  1. Can I preserve the posting dates?
  2. Can I just relink post/comment attachments?
  3. How to cope with @mentions and Likes?
  4. What will such a migration do to reputation scores?

I ended up building my own tool which can be found on Github:
