First update for Opera Next 15 has made user profile migration feature available for Opera 12 users. User can import his profile in Opera 12 containing history, cookies, speed dial, bookmarks, and settings related to passwords and search engines to Opera Next 15. Users here should know: once migration completes Opera next 15’s profile will be lost as it will be replaced by Opera 12’s. And Opera 12 profile’s bookmarks will be available in bookmark importer, which can be found from Opera menu>More tools>Bookmark importer.
