moved my blog, path problems

so I’ve moved my blog from 1 host to another, and I guess I need to update the path in my config files, but I don’t know where to do this..

my absolute path was:
/usr/local/www/htdocs/zzzz/xxxx/

now its:
/home/users/web/zzzz/xxxx/

can someone tell me where I need to update this in my wordpress config files, please…

Thanks,
Greg
