To Find and Remove Earlier Tar-Based Installed Message Queue

1. See if the default Message Queue installation directory (/opt/imq/bin) exists on your system.

   If not found, Message Queue might have been installed in a non-default location. If you cannot remember the installation directory, search for the Message Queue imqbrokerd executable and note its root install directory.

   If there is no previous Message Queue installation, proceed to install Message Queue by following the directions in Installation Procedure.

2. If you find an earlier Message Queue installation in the default location (/opt/imq/bin), remove it as follows:

   1. If you want to preserve existing broker instance data, run the mqmigrate utility (in the Message Queue 3.7 UR1 distribution) as described in Migrating Files from an Earlier Installation.

      The mqmigrate utility moves existing broker instance data (broker configuration files and persistent data) and security-related files, to new Message Queue 3.7 UR1 locations.

   2. Remove the /opt/imq/ directory and all its contents.

      rm -rf /opt/imq
