Hi all, Im new using plesk and I want to kknow some issues.

Its possible upgrade my version of plesk, im usgin version 8.1 and running RHEL 4.0 upgraded to Centos 4

How I can change horde to squirrelmail, I try to install it using yum but it install centos version and I want the psa version, I think i need to install atomic psa to install it or upgrade to psa 8.2.1?

Sure, you can upgrade Plesk. Use the Plesk Updater via the web interface, use the autoinstaller script or use yum if you have ART's Plesk repository configured.

SquirrelMail is not part of Plesk, but I believe people have hacked it up so that SquirrelMail is used when going to webmail.example.com. I believe you should probably be able to find howto's on forum.swsoft.com, but I have never used those.

Myself, I just installed the squirrelmail package via yum and configured it. By default SquirrelMail is available at example.com/webmail. In this way I have both Horde and SquirrelMail available.

I have plesk 8.1 who came with my server in rackspace, how to convert this version to psa atomic version?

There is no special atomic version of Plesk.

You can add the atomic yum repository to your yum configuration though, so you'll be install the third party packages created here (PHP 5, MySQL 5 and some other packages that are not part of Plesk itself).

Run wget -q -O - http://www.atomicorp.com/installers/atomic.sh | sh to setup this yum repository. Also see the wiki for more information on for instance upgrading to PHP 5.

You also might be interested in Atomic Secure Linux, which is a security solution for Plesk servers.

Sure, I have upgrade to php5 and other atomic packages via yum, now I want to know how to update to plesk 8.2.1 via yum within affect my server and domains clients, also install app vault and other nice app

You'll have to add the Plesk repository to your yum configuration: http://www.atomicorp.com/channels/plesk/

Though updating using the Plesk Updater or autoinstaller should work just fine as well.
