I'm a long time Google Apps for Your Domain (GAFYD) user. That means that hanselman.com email, calendars, etc is all handled by Google Apps. I've got dozens of other Hanselpeople (relatives and others @hanselman.com users) on this system and it works nicely.
When Google+ came out I signed up, but for the first several months the Google+ social network didn't allow Google Apps users to signed. Only Gmail.com users and folks with regular Google Profiles could sign up. So, most of us with Google Apps created temporary Google profiles or throwaway Gmail accounts in order to sign up. We were told that there'd be a migration tool "in a few weeks."
It's been almost exactly a YEAR from the first time this was announced. Last week they announced a migration tool via their "Google Takeout" system.
Fast forward several months and Google has announced the migration tool for Google+ users who want to migrate to another account. The tool is under the Google Takeout system which "Google Takeout allows you to download a copy of your data stored within Google products."
Unfortunately this new migration tool only supports downloading and migrating your Circles, but not your posts, comments or +1s. Compare this moving accounts or URLs under Facebook and Twitter, each of which allows you to change names without losing followers or posts/tweets/notes.
So, this means that while I can move my Google+ account and followers/encirclers over to a new account, all my posts will remain on a vestigial parallel-universe Scott Hanselman who will live forever. I've got a year of posts, great comments and thousands of +1s that are trapped in another social walled garden. I'm forever Scott Hanselman on Google+, except when I'm Scott Hanselman on Google+.
Even worse, my existing Google+/Google Profile account is already associated with all my blog's content on the Google Search Engine. This now makes one wonder if I move my existing authorship metadata to the new account will it work? Blog authors rely on rel="author" as a way to indicate their legitimate content is written by a human.
I've posted my dismay on my Google+ account. Google Developer Evangelist Chris Chabot kindly responded and said:
Posts and comments are not lost, they remain as they were - what is the case is that we don't rewrite history by changing the name above those comments. ie if you commented as "Scott Hanselman" then that name will remain above the comment / posts you did.
I imagine that otherwise it would get pretty confusing if we did try to rewrite history - for instance if someone responded to your comment and said "Hey Scott Hanselman thanks for the info!" but the comment now had "Bob" as a name on it, there's no correlation between your posts, comments and their replies anymore.
So - nothing is lost or removed, there's just the side note that we also don't go back and try to rewrite every post, every reply and +mention that was ever done.
However well-meaning, I think Chris is missing the point of the audience who needs this feature. No one is trying to "rewrite history." We're just trying to move an account from one login to another. Even better if we don't need to change ANY URLs. I don't want to change URLs, move my profile or anything. I just want to login with different credentials.
Here's my response to Chris and Google, reprinted here.
This is a permalink issue not a "rewriting history" issue. I'm Scott Hanselman on a throwaway gmail. That's me here. I want to move to my Hanselman.com account where ALL my social media is (until g+). That is your primary use case and primary reason a GAFYD user would move. I want to simple change my login, from my perspective. For you, it appear this is a data migration issue as you're making week-long data moves. We just want to change a profile login.
Secondarily, I've got rel=author working nicely in google today. If I move, I'll need to change my authorship and hope Googlebot notices it in a few weeks. This is a perfect example were a 301 redirect from my old profile to my new one would go a long way.
Does this help clarify my position? I'm absolutely convinced this is the primary way folks would use this migration and I can say that all my peers and folks I've talked to expected a cleaner migration.
I want to move from my throwaway to a paid GAFYD account and it's [not really] acceptable to have hundreds of posts laying around NOT attached to my legit and primary account.
There are also a number of unanswered questions. What if someone finds some G+ posts from the last year and encircles my OLD account? Are they redirected? Likely not. I have hundreds of links pointing to my profile on the web. Why not 301 redirect those? Or, better yet, don't change the URL!
I believe that Google+ really needs a better system for their early adopters like myself. I've got a year worth of content and almost 40k followers on Google+ and I just want to login with my primary Google Apps account - the account I use for everything.
