cmigrator did the job as expected, thanks
Only things I'm missing, is migrating post icons to Joomla articles "Intro Image"
Another thing is url redirections from WP to Joomla.
First should be easy to do, second might depend on local configuration.
As I'm in hurry... is there any log of migration available? Any info on with Wordpress post, became with Joomla artile, by IDs?
