I was just wondering this myself. Is it a matter of just copying all of the files from your root directory? Or do you have to transfer over the contents of the mySql database too?
1.) First, just FTP the entire Plogger folder onto your local hard drive - keep it there you will need it later. 2.) On your old web host, go into phpMyAdmin and click the export tab on your database. For Plogger, you just need to export the tables with the "plogger_" prefix. Make sure you have "DATA" checked too on the export options. 3.) On your new web host, create a database with the same name as your old one and import the SQL dump from the previous host. This should duplicate the database. Make sure that you setup a new user to access that database as well. If the database name, username, or password is different for the new database you will have to modify the plog-config.php file with the new parameters. 4.) Use FTP to upload Plogger from your hard drive onto the web server of your new host. Make sure the folder permissions are set properly on the new host as well... check the installation guide if you don't know which folders need to be writable. 5.) Try logging into you new Plogger administrative panel.
