I currently have a site with around 9000+ articles, with images, users, categories, tags, etc. currently on a Joomla 2.5 K2 website and looking to move everything to a new site template running J 2.5 with K2.

What is the best was to move over all the articles, images, users, categories, to the new template?

I would just add the template to my current install, but the new template is vastly different as it's a responsive site, with different framework, and plugins to run the site. I already have the quick install up and running and have everything setup, I just need to move the information to the new install.

Thanks for the help!

+1 on this question. About to upgrade to a new template. Probably one of rockettheme´s latests. At the moment i use an older RT template called afterburner. Joomal 2.5. I also run a virtuemart webshop on the site. Have been adjusting the K2css a bit too to fit the dark background. Thank´s for any advice on what to consider when updating the template!
