Great question! This will be a very tricky task and we need to be really careful about it. We will need to reach out to every single user of the 50k blogs and ask what's best for them. Some of them just want their blog posts' archives, and we will help them with that. Some others would love to have a new home for their content, in which case we will help them get on Steem! We will delegate SP to their account to help them get started, and we will reach out to the community for help if we ran out SP.
