Can I install Expedite Base/AIX 4.6 on the same system as an earlier version?
If you have any two versions of Expedite installed on the same system, you must be careful not to use the same Information Exchange account and user ID with more than one of the installations, or to take special precautions to manage session recovery across the separate installations. The presence of session.fil indicates a session is in checkpoint recovery state. Do not start a session with one version if there is a session.fil file associated with another version using the same Information Exchange account and user ID. Both Expedite and Information Exchange maintain session information. If you start a session with the installation that is not in checkpoint recovery state, this new session will cause Information Exchange to delete its previous session information so it can proceed with the new session. The installation in checkpoint recovery state will be unrecoverable.
