Change MySQL port 3306 used by plesk

[moulzed]

Hello,
I am a little bit newbee in this forum and as a user of PLESK.

I am using a win2003 web server with Plesk 7 as administration interface. I want to set the mysql port used by plesk to another value than 3306. (We need this port because some clients softwares needs communication through this port number 3306).

How can I do ?

Thanks for your help

Moulzed.

Happy New Year.
