Since the migration tool does not preserve the original publication dates, this would explain why your latest blogs have become the oldest ones after the migration process (since they were processed first). There used to be a similar scenario with News items. A possible solution is to implement a custom field for your blog posts of type DateTime,s o you'll be able to easily specify the original date of the post. Once you've set this you can run a sample code which will set the publication date (displayed on frontend pages) and date created (displayed in the backend for the particular post) to the value in that custom field. Actually, you can try to implement the code from this forum thread
, I believe you will find it useful, you'll just need to change the reference to Blog posts not news items.
