h2. Desired workflow for migrating ISO content 

 h5. 1. Create a migration plan by POSTing to */pulp/api/v3/migration-plans/* the following JSON. 

 <pre> 
 {   
     "plugins": [  
        { 
          "type": "iso", 
          "content": true, 
        } 
     ] 
 } 
 </pre>  

 h5. 2. Run the migration plan  

 POST request to */pulp/api/v3/migration-plans/asdf-2345-ghjk-4567-adc/run/* 

 h2. Implementation details 

 The migrate_from_pulp2 task[0] needs to be updated to do the following: 

 1. Query the Pulp2Content model for: type='iso', pulp3content=None 
 2. Dispatch 36 'migrate_content' coroutines with 1 parameter: content_queryset - a slice of the queryset from step 1. 
 3. For each unit discovered, the coroutine will do the following: 
 * create a hard link in /var/lib/pulp/artifacts/ directory 
 * create Artifact in the Pulp3 database 
 * create FileContent in the Pulp3 database 
 * update the Pulp2Content model with a reference to the FileContent
