Perform the following steps to complete a tarball upgrade on a single server configuration. This is not a typical upgrade. You will install PureMessage version 6 alongside your existing 5.6.1 installation, and, optionally, migrate data from version 5.6.1 to the newly installed version 6.
If you plan to migrate data from your existing installation to version 6 using the PureMessage migration script, you must already be upgraded to 5.6.1. For more information, See "Upgrading to PureMessage 5.6.1 from a Tarball Distribution" and "Migrating from Version 5.6.1 to 6."
If you are upgrading multiple PureMessage servers, also refer to "Multi-Server Upgrade" in "Upgrading to PureMessage 6."
Following an installation or upgrade, you must reconfigure PureMessage so that it retrieves future updates and upgrades from the correct Sophos repository.

During installation, a symlink called "pmxrepo" is created in /opt/pmx/home/ that points to /tmp/pmxrepo. Once your tarball installation is complete, you must remove this symlink to ensure that updates are retreived from the repository that you specified in the procedure above.
