There is a process for migrating your Google+ Business Page With Google+ Local and verifying your Google Place page as a Google+ Local page.
It seems like part of that is not available to Google Apps users. Which is funny to me, because I’d assume a nice percentage of folks who need to manage Google Places / Google+ Local are Google Apps users. They are business owners.
That being said, Jade Wang from Google said Google is working on giving Google Apps users access to verify their Google+ Local pages.
She wrote in a Google Business Help thread:
How soon? I’d guess a year or two. (sarcasm maybe)
