Hi we had an old joomla site with k2 and over 20.000 articles.

We moved to a new joomla installation with latest joomla and k2 editions.

We manually insertes k2 items from db and moved the images from old to new.

In some articles some images are missing .

Instead of showing image it shows a text like "DC0515" maybe the name of the image.

How could we do a correct migration from k2 to k2?
Thanks

I would break it into chunks and try this tool
www.individual-it.net/en/Joomla/#27

This is not really K2's main image, maybe an image inserted in the editor, so make sure to check the image's path and copy that folder as well.
