upgrading to parallel plesk 9.0.1 from 7.5.4

I have centos 3.8 and plesk 7.5.4 and near 1000 clients.

I want to upgrade centos to 5.2 and plesk to 9.0.1 now(with switching to postfix).
Is it possible to do without hard caveats? OS+Plesk upgrade.

Does any solution exists?

or would it be better to configure new fresh Server with fresh centos installation and plesk9 and then just move clients from old server to new one via PLESK-backup/restore tool?
