I got the email that saysUpon reporting this latest support need to Blogger, I was advised of the sad reality, by a Blogger Engineer.You are receiving this message because your email address is associated with an unmigrated legacy Blogger account. As we announced in April of last year, legacy accounts will no longer be accessible after May 30th, 2012 unless they are updated to the Google Account system. Any blog content associated with this account will also be unmodifiable after that date.
Legacy support has been deprecated.We have seen this coming, for a long time - and it has finally arrived.
It's possible that the Legacy Claim form may help you - though the queue for action can be a week, or more. Here, as always, you have a much better chance of success if you know both the Username and Password.
Alternately, if you can setup a new Blogger account, try recovering the blog into the new account. Alternately, checkout the Known Blogger Issues article, for some possible solutions.
Other than that, let Blogger move into the future - don't demand special treatment, which will only help enable future opportunity for account hacking.
What this advice means is simple - if your blog(s) are owned by a legacy Blogger account, that account, and blog(s), is now frozen, if the Claim Form is not useful.
- You can't convert your account.
- You can't update your blog(s).
- They won't delete your blog.
- They won't take the URL away from you.
- You can't delete or update the blog - or re use the URL.
If you wish to publish using Blogger, start a new blog, under a new Blogger account. If you're here because you have not published your blog since 2006, the changes to Blogger have been so extensive that you'll be starting over, anyway. Start a new blog - you can always include the old blog, in the new one, as static content.
(Update 2015/05): It appears that the deadline has passed, for some remaining unmigrated accounts.
