MTA Configuration

The MTA upgrade configuration sub-script that makes up of part of the do_the_upgrade.sh utility is called make_mta_config_changes.sh (located in /var/tmp/UpgradeMsg5toMsg6.ScratchDir).

The make_mta_config_changes.sh script backs up, renames, and moves the *.MERGED server configuration files to their original names and locations within the current version of Messaging Server file directory structure.

Once the script has finished renaming and moving the files, it automatically runs the imsimta cnbuild command to recompile the MTA configuration.

If you want to upgrade an MTA relay machine from Messaging Server 5.2 to the current version of Messaging Server, you only need to run the make_mta_config_changes.sh and the make_backup_config_changes.sh (described in Backup Configuration).
