Good to know the GMail->Apps migration tool is still being worked on, but rather disappointing to learn it won't migrate posts, making me unlikely to use it. Google Plus hasn't exactly embraced Google Apps users, which is why I'm still switching over to Firefox to use Google Plus.

Says +Ronald Ho in comments to linked post:
the migration tool that our team is working on will not migrate your content like pictures and posts. We're working to make sure that your connections can be merged, so that you can move your circles from one profile to another and ensure that followers of that profile will now be following your new profile.
