Drush site upgrade: Contributed extensions were not upgaraded I am using Drush site upgrade module for D6 to D7 Upgrade.

In step 15, drush asks me to update only one module i.e. path_access, and for all the modules it says "following contributed extensions were not upgaraded". Then in final step its says "there are no more modules to be upgraded".
And my all contributed modules remained unupgraded.
Should I need to upgrade them manually.
I think you should Migrate d2d module for content migration and also should upgrade contributed modules manually as might be some modules aren't supported in drupal 7. So, this should be a manual task. But using Migrate d2d module, you should be able to migrate content :).

I guess this is helpful to you.
