将整个joomla站点移动到另一个directoy / subdomain

I am currently developing a joomla 1.5 based site in a temp subdomain (which points to a subfolder on ther sever where all joomla stuff is installed). Currently I am using plugins joomgallery an kunene 1.0.9 (legacy mode). Once the development is done I would like to move the whole site into the root directory and delete the whole subdomain. How would this ideally be done? Can I just move the files or is there more to it? Any common pitfalls to watch out for? E.g. Are there absolute paths referenced somehwere?I am currently developing a joomla 1.5 based si
