I became unhappy with our host for the website, and had to transfer all the wordpress gumpf… here is my method that worked:

Transfer wordpress from one webhost to another

1. copy across the files – I managed to ZIP them all on the server side, and then download the one zip file, extract it, and upload the individual files
2. Extract the database – use PHPmyAdmin to extract the database (ZIP it), make sure you only extract the data, and not the structure/schema as when you try to import it, it’ll throw up an error and go no further.
3. create a dB and user – with the same names, if not, you’ll have to do a search-and-replace on the .sql file and change everything over
4. import that database
5. customise the wpconfig.php file, you may need to change the address it resides, and the FTP username/password for the new host.

It should now just – work!
