I have wordpress blog site and I am migrating it into Wordpress multisite. We have more then 4000 users and approximate 3000 post and comments.
My requirement: Every existing user have their blog automatically. Like user jay have their blog example.com/jay or jay.example.com with their existing posts, pages and comments.
Suppose my blog website(not wp multisite) is http://www.myblogsite.com with 100 registered users.
raj, jay, rahul, tony etc etc.
User raj have 10 posts, 2 pages and 5 comments.
All post of user raj are showing on http://www.myblogsite.com/author/raj url.
Now, I want to migrate wp single site to wp multisite.
Then raj got thier blog automatically and url would be http://www.myblogsite.com/raj and all posts of raj showing there and pages as well.
My Question: Is there any plugin or script to export data from wp single site and import it into wp multisite so all users get their blog automatically with posts, pages and comments.
