I have used this extension to migrate a site.
The basics were migrated, but i needed to migrate a Kunena forum as well.
Bought the kunena migration plugin, but it didn't work at all. Wrote in the forums and others had the same problem. I was contacted and gave them the details they needed to find the problem. They replied they would look into it. Now several weeks later i have't heard from them and they don't answer my mails.
I have migrated the Kunena data manually now.
The download was from the redcomponent website
I use it on all sites with login posibillities.
When upgrading the site i looked for some alternatives as there were som minor things that annoyed me.
But i kept getting back to DOCman. I have used the 2.0 version on another site and it looks great !
Now i can't wait for the migration tool to finish so i can get the DOCman 1.6 upgraded to 2.0
It truly has a lot of potential.
That said i found a bug that stoops me from using it as i can't select events.
It has been reported but the support is not existing. No answers at all.
I am dissapppointed as it isn't the cheapest extension. Not recomended if you want to use it right now.
