Dear Support Team
I plan to Change my web hosting So that without losing any data and user names change to new hosting how ?
A very comprehansive tutorial is made in tutorials section of this forum
1. Make full database backup and download all of your files.
2. Edit Board URL and cookie settings to what they will need to be if your domain is changing too, leave them as they are if it isn't.
3. Upload the files to new host.
4. Create new database, import backup to it.
5. Edit ./inc/config.php to point to new database.
