I'd like to migrate my Yahoo group to a newly created Google group. We have ~60 users, 5K messages, as well as photos and documents. I found that there are several tools that enable downloading user data and have used one, PG Offline to do that.
Now, I want to find out how to migrate the Yahoo data to my Google group. One suggestion I found was to get the data into a SQL database. Sadly, no details were provided.
What I'm hoping is that someone who's done this successfully can describe, in broad strokes, the methods and tools they used.
Is the Google Groups Migration API the place to start? Thanks!
