moving an entire easyblog - site re-developement

Hi Easyblog,
i am after some advice please

i have a client with a current joomla / easyblog CMS

im in the process of developing a new site for him - i would like it to include easyblog - i would like to transfer his entire easyblog - posts - images and settings etc to the new site (currently on a testing server)

how can i achieve this if easyblog is tied to a domain name (he will have two for a short while while his new site is in development)

what method do you suggest for moving the entire easyblog

thanks for your help

;-)
