Upgrading PHP4 to PHP5 Plesk 8.6 Centos 4.8

[MatrixAce]

Hi everyone,

Just want a confirmation.

Is it safe to upgrade php4.3.9 to php5.2.*? And Mysql 4.1.22 to Mysql 5.0.87?
I've a Centos 4.8 box with plesk 8.6 installed.

Please advice...

I would not dare/want to try until someone can give me an answer. =D

As there's a lot of domain in my server... and I don't want risking screwing up the whole box...

Please understand. Thanks.=)
