Hi, I purchased the service to be able to use your extensions, in particular I am interested in k2 migration to joomla content.

I am following the instructions that are contained here:
https://www.joomlart.com/documentation/joomla-plugins/k2-to-com-content-migration-plugin

Unfortunately the migration doesn't work.
I have to migrate around 13,000 articles and 400 tags, as well as some extra fields.

If I stop at the "installation" chapter, you mention 4 elements:

JA K2 Convert plugin
JA Content Type plugin
JA Ajax Content type plugin
JA K2 to com_content migration package

But I've in my installation this one:

System - JA Content Type
Ajax - JA Content Type
JA K2 To Com Content Migration

In the download area of your site I didn't find anything else to download.

With the first attempt, it reported a problem because there were empty tags.
I restored the backup, deleted all the empty tags and started following your guide, but when I open the popup window it stays blank and nothing happens.
While I am writing to you I saw that something was partially imported, but for example the extra fields were not imported.

If I try with the second procedure (I don't understand if I have to do them together, first one and after the other, I can't find the specification in the guide) "migrate extra fields" an error appears.
