This is the step-by-step tutorial to move tikiwiki from one host/hosting to another host/hosting :
1) Dump the database, using something like phpMyAdmin to a SQL file
2) Delete all in your local copy of templates_c
3) FTP your local tiki root to the hosts webspace
4) If you dont have SSH access CHMOD the necessary directories and files using FTP otherwise SSH in and run ./setup.sh with the correct parameters
5) Create your database by running the dumpd SQL file on your hosts db server
6) edit the db/local.php file and enter your new database connection settings
