I know how to move a site to another server, but the process i guess is a little different when it comes to moving the wordpress and DB to another domain. If anyone is able to do it please let me know, i need this done asap! $$
If you are using cPanel then download a full site cpmovefullbackup file and transfer it to the new server and restore it from WHM or tell your host to restore it. That is the simplest way without SSH access (assuming you dont have it). If you are not using cPanel or your new host does not want to move it for you (even through SSH or cpmove) then compress all the files and content from the folder where your content lies (public_html for cpanel mostly, www for many other panels etc.) and download the zip or tar.gz file to the new new server. Similarly, make a backup your database with phpmyadmin or through cpanel if you have access and move it to the new server and restore it. Or you can also try a plugin like this. http://wordpress.org/extend/plugins/xcloner-backup-and-restore/ Never used plugins to do that and so not sure of the result but that seems to be popular and so might do the trick if the above sounds a bit alien to you.
if you want to change the domain name also. You need to perform some sql queries as wordpress stores absolute paths of url. So These SQL queries for administrator must be performed to change the URLs.
I will do it , within no time and without any loss of a single file. Pm me for my contact details if you still need this job to be done.
