The Menu trails module that is used for giving content a suitable position in the Drupal menu lacks a Drupal 7 version and it doesn't work all that well with multilingual sites. The Menu position module provides equal functionality, is still supported and even works better for multilingual sites.
I wrote a small drush command for migrating to Menu position. It will convert Menu trails rules to Menu position equivalents. In the simplest case you can just install the command to the ~/.drush directory and run "drush mt2mp".
Additionally the "drush mpclear" command can be used to remove all rules configured for the Menu position module. The code can be found on Github.
