At the moment we have a server running 5.0.6 that has never had zimbra-proxy installed. We're just adding a second (then third, then...) server and would like to use the proxy functionality.

How do you go about *adding* zimbra-proxy to an existing installation? I've been looking at the configuration on the Multi Server installation guide (p23-26) and that's all fine, but do I just rpm -ivh zimbra-proxy first or does it have to be done in a more Zimbra-ish way?

If I'm missing an obvious piece of documentation and you can point me at it, it'd be much appreciated.

Thank you,
