In my J1.5 site I have removed a lot of plugins, modules and components that will not work in J2.5 & upgrade everything else to be J2.5 compliant, Including K2.

I have tried to upgrade to J2.5 using jUpgrade as advised by Simon Wells in another post.

Everything upgrades well and once ive installed the new template for J2.5 and tweak a couple of bits the is looking along the normal lines again;

BUT - K2 doesn't seem to upgrade over?, I have tried from 2 test backups of my site one using K2.5.7 and one using k2.6.1, neither of them work?

Is there a setting I need to have made in order to copy K2 over to the new J2.5 environment?

Thanks
Andy

I would try with the k2 2.5 site and then move up further
first get your 1.5 site up to k2 2.5, then run the upgrade
as i remember there is a post here somewhere with phpmyadmin sql statements that are necessary after the upgrade
first check with phpmyadmin and look to see if your items are in the table k2_items
see here getk2.org/documentation/tips-a-tricks/item/311-manually-migrating-k2-content-from-joomla-15-to-17
