How to refresh new migrations in Drupal 8 migration module? When writing Drupal 8 migrate processes I only can refresh new migration processes if I reinstall the custom migration module. drush cr doesn't work.

Explanation:

I have one module, ie: cm_migrations, which have 2 migrations:


cm_users 
cm_tags


With drush ms I see:

Group: beer     Status  Total  Imported  Unprocessed  Last imported       
 cm_users        Idle    3      3         0            2016-02-09 16:56:25 
 cm_tags         Idle    4      0         4                                


I write a new migrate process: 


cm_beers


I execute drush cr; drush ms and I see the same table as previous. 

Only when I uninstall and install cm_migrations I can see the three migration processes:

Group: beer     Status  Total  Imported  Unprocessed  Last imported       
 cm_users        Idle    3      3         0            2016-02-09 16:56:25 
 cm_tags         Idle    4      0         4                          
 cm_beers        Idle    4      0         4              


Any clue about  how can I refresh the migration processes without reinstall the module?

Thanks
I found this worked for me


  drush config-import --partial --source=modules/custom/migrate_module/config/install/
