OMG, what a great product you guys pulled ! Really fresh

Congrats !
Quick question:
I updated the old EasyBlog version to EB5 and everything seems to be working perfect except that for "old" blog posts.
It seems that for old blog posts the "blocks" feature is not activated and also those post load up with the old WYSIWYG editor.
How can i "migrate" those post into the new version ? I am interested in particular in the gallery feature, the "old" gallery mode (folders of pictures inserted into blog post as "gallery" thru the old media manager, old way of doing it

) is not working anymore and all that shows up is a shortcode
Any solution on how can i re-apply the gallery feature for old post into EB5 ? Thx !
