I just wanted to add to this since I’m less sleepy now.

In case you don’t have or don’t want to use shell access, the process is just to:

- Backup your database. Make sure your backup is in “sql” format, NOT xml! An “export” from WordPress’s dashboard won’t help you.
- Optional: Take your site down while you run the conversion. If you don’t, your site will mostly just appear slow, timeout, or possibly return an error page (depending on how WordPress handles database contention).
- Copy that php file from above to your wordpress install directory.
- You can run it in a browser if you don’t have shell access.
- If successful, remove that php file from above.
- If not successful, remove the php file from above and restore the database from your backup.

Oh yeah.

If you don’t know your mysql login creds, they will be in your wordpressinstalldirectory/wp-config.php.

Look for values db_name db_user db_password. db_host might be relevant as well. my previous example assumed that the database was running on the same host as the webserver. If the mysqldump command fails, add ” -h valueofdb_host” and you should be good.

One final thing – omit the “http://” when you ssh to yourusername@www.neptunuslex.com“

This is pretty simple if you know what you’re doing.

Connect to your webhost via shell or CPanel/PhpMyAdmin. Example below is for shell access.

ssh -l yourusnername http://www.neptunuslex.com
enter password

mysqldump -u yourmysqlusername -p yourmysqlpassword yourdatabasename > backup.20090614.sql

copy the php file referenced at “http://www.mydigitallife.info/2007/06/23/how-to-convert-character-set-and-collation-of-wordpress-database/” to your wordpress install directory, and run it:

wget http://forums.mydigitallife.info/attachment.php?attachmentid=34&d=1182541079 > wordpressinstalldirectory/fileijustsavedTowordpressinstalldirectory.php

(the wget command actually will probably not work since that site wants you to be acually logged in; you’ll have to save the file locally and copy it to your wordpress install directory on your webhost).

cd wordpressinstalldirectory
php fileIjustsavedTowordpressinstalldirectory.php

And maybe it works.

If it doesn’t work:

mysql -u yourmysqlusername -p yourmysqlpassword yourdatabasename < ~/backup.20090614.sql

will restore your previous database.

Good luck!
