Basically you need to convert your MySQL5 db to a MySQL4 db. Heres the steps I recommend: 1. Reverse the process so you're running MySQL 5.0 again. 2. cd into the /var/lib/mysql directory. 3. run the command - mysqldump -uadmin -p --compatible=mysql40 --all-databases --add-drop-database > /databases.sql This will ask you for your Plesk admin password and then dump the contents of the databases in a format compatible with mysql4. Make sure you are root while doing all this, because it will save the databases.sql file in your root home directory. 4. Downgrade again to MySQL4. 5. cd /var/lib/mysql and then rm -rf * BE CAREFUL. you only want to empty out the /var/lib/mysql directory. 6. Make sure your mysqld is running and then do this command - mysql < /databases.sql - then restart the mysqld again. Hopefully this will get you running MySQL4 with your databases in the MySQL4 format. Temi,

BE CAREFUL. you only want to empty out the /var/lib/mysql directory.

6. Make sure your mysqld is running and then do this command - mysql < /databases.sql - then restart the mysqld again.

Hopefully this will get you running MySQL4 with your databases in the MySQL4 format.

When I start the new service it starts but it breaks Plesk and I get this error: Service is not available now, probably your Plesk is misconfigured. Contact Your provider for details. Internal Plesk error occurred: MySQL query failed: Table './psa/misc' was created with a different version of MySQL and cannot be read What do I do now ?

Exactly what I needed and all is working great. I would only add that if you are going to be doing more database work from the command line you should put one more line in my.cnf: [client] socket=/var/lib/mysql/mysql.sock Thanks!

You'll need to just find the old version that you want from their website. Otherwise you can follow the instructions in this post, and it should work. Temi,

I have a Plesk server that comes with MySQL 5.0 by default but my website requires 4.1. Would you by any chance know if this would work for downgrading from 5.0 to 4.1?
