Migrate s9y posts
– use import from RSS, rss = http://blog-s9y.hostsname.sk/feed/rss.php?version=2.0&all=1
And then update to whole body:
UPDATE wp_posts w, sp_entries s
SET w.post_content = CONCAT(s.body , '<!--more-->', s.extended)
COLLATE utf8_general_ci
WHERE w.post_title = s.title COLLATE utf8_general_ci ;
