Hello,
I have a website that I've got about 50% developed and the client all of the sudden found a new template they like more. The problem is that it is from a template club and to keep from having to figure everything out I wanted to use the install they provide with all the goodies already in and working.

Is there are way to migrate the data from K2 from the one site into the other? Like all the Categories and Items is what I'm curios about right now.

I think it is as easy as exporting/importing K2 tables between the databases, and copying/synchronizing the contents of folder media/k2/

Although, you need special care of users if there are users created on the old site.

Frank- Did you ever do as suggested? I'm curious to know how it went.

Mohamed Abdelaziz is totally right. As long as you have the same versions of Joomla! and K2 in both sites then you just have to copy the K2 database tables from one database to the other. After that copy also the media/k2 directory and everything should work fine. Note that this refers to K2 only. Menus and modules will have to be created again.
