In Another Complication In Migration - Team Blogs #2, we noted a thread by Buzzer, where a problem with team blogs was, supposedly, solved.
We modified our migration algorithm to handle this case correctly so other users don't fall to the same trap.
Today, in Will I ever be able to access my Blog?, we see a report of a team migration attempted on 12/12, a day after the forum post, quoted above, was made.
I don't think that we're out of the woods yet, folks. Looks like the extra effort, as described in my systematic migration procedure, may be worthwhile after all.
