A MID Server configuration parameter called mid.upgrade.run_precheck is set to true by default, which allows the automatic pre-upgrade test to run. To disable these tests for a single MID Server, add this parameter to that MID Server's config.xml file and set it to false. To disable these tests for all MID Servers, add a new record to the MID Server Property [ecc_agent_property] table called mid.upgrade.run_precheck. Set the value of this property to false and leave the MID Server field blank.
