Commerce kickstart upgrade
i have the commerce kickstart 1.3 installed but i see that there is kickstart version 2.6.
My question is do i need to upgrade? will it give me additional usability? i am updating regularly the modules that i have separate installed. and if i need to update how is that possible are there any steps? should first update to last version of commerce kickstart 1.X and then to 2.6. in update section there are not clear instructions.
another question is about omega kickstart theme.
i have installed it separately how i can achieve the functionality as is on the demo site is there any tutorial for that?
