Restore components and resources that you have migrated from Version 2.1 products back to their original version.
The following sections describe how to restore the Message Brokers Toolkit and runtime components to Version 2.1.
Use the -s and -t parameters of the mqsimigratecomponents command to migrate components from Version 6.0 to Version 2.1. Specify Version 6.0 for the source version parameter (-s) and Version 2.1.0.8 for the target version parameter (-t). See the mqsimigratecomponents command topic for detailed information about these parameters and the format to use when specifying version numbers.
mqsimigratecomponents Broker -t 2.1.0.8

If you restore the Configuration Manager to Version 2.1, you must also restore the Message Brokers Toolkit and any brokers to Version 2.1.
The Version 6.0 Configuration Manager does not use the DB2® database that was used by the Version 2.1 Configuration Manager; if you restore to Version 2.1, the original database is used again. Therefore any configuration changes that you made after you migrated the Configuration Manager to Version 6.0 are lost. This earlier level of configuration data can leave your domain in an inconsistent state, forcing you to rebuild and redeploy all of your brokers in order to regain a consistent state. After you have migrated your Configuration Manager to Version 6.0, check carefully that the Message Brokers Toolkit and Configuration Manager are working correctly before you attempt any further configuration changes, or before you migrate any brokers.
If you have moved the Configuration Manager queue manager during migration, you must keep the new queue manager when you restore, unless you restore your entire domain from a backup. If you have moved the Configuration Manager onto an operating system other than Windows, you cannot restore it to Version 2.1 unless you restore your domain from a backup.
mqsimigratecomponents ConfigMgr -t 2.1.0.8
Your Version 6.0 Message Brokers Toolkit will
no longer work; you must use a Version 2.1 Control
Center instead.
