Swapping database vm2

[kinseymark]

Hi all,
Ive developed a site in Joomla 1.5 which uses virtuemart however I'm upgrading to joomla 2.5 but doing a fresh installation as I'm not confident is overwriting files. Therefore I want to export the database from my original website which contains all my images, prices, descriptions etc and import this into my new installation which operates the latest joomla and vm.

My question is how do I do this, can someone please supply me a step by step guide. My orinal website is www.puxels-direct, my new website I'm testing on is testingmypixels.info.

Sorry just checked my original post and noticed that my first url is wrong it meant to be www.pixels-direct.co.uk
