Retro Change Log
When you migrate the configuration in verbose mode, dsmig issues a warning indicating which system plug-in configurations are not migrated.
Plug-ins that you have created are not migrated. However, during the migration process user plug-in configuration data is dumped in the file new-instance-path/migration/old_userplugins_conf.ldif. These plug-ins must be recompiled when the migration is complete.
