howto downgrade php 5.3 to 5.2 on Ubuntu 10.04/Plesk 10.2

[RuudNetideas]

I've got a Ubuntu server (10.04LTS) with Plesk 10.2 (clean install).

Server is installed with PHP 5.3 but I need 5.2 to get vTiger to work.

Whats the best way of downgrading PHP?

I've tried several ways as described on the Internet and even this forum but this ended in a non-working system and I had to re-install EVERYTING.

HELP Please.
Ruud.

Upgrade to vtigercrm-5.2.0, any PHP software that doesn't work with PHP 5.3 has security holes. register_globals is a very bad thing.

Or I did just follow the direction in post #7 about two week ago, downgraded without an issue. But again, PHP 5.2 should not be running on any production servers anymore. The major repos are not issuing security updates for 5.2.x, only 5.3.x.

But I highly suggest upgrading vTiger instead.
