Upgrading from Previous Versions

To upgrade from prior Message Queue versions, it is recommended that you first uninstall Message Queue software as described in the Message Queue Installation Guide of the appropriate version, before installing Sun Java System Message Queue 3.7 UR1.

If you want to preserve data from a previous version of Message Queue when you migrate from an older version, refer to Migration Issues prior to uninstalling Message Queue.

If you are installing Message Queue after a previous uninstall, check that any references to the previous Message Queue installation have been removed from the system’s PATH environment variable.
