Upgrade Mysql version? any doc or info ?

[kadoudal]

I am currently running Debian GNU/Linux 6.0 Plesk 10.4.4 ( Update #27, last updated at April 23, 2012 )
MySQL installed is
mysql Ver 14.14 Distrib 5.1.49, for debian-linux-gnu (x86_64) using readline 6.1

I would like to upgrade to version 5.5 of MySQL... I guess running mysql-upgrade is not enough , and I should take care of some other things related to Plesk 10 ?
any doc or at least some successful post ?

thanks for feedback

Mysql package is not shipped with Plesk but it only downloads it from original OS vendor repo and it is quite likely it may be outdated there (especially for older OS). If your OS comes with fresh version of Mysql, then Plesk would run this Mysql version.
