Issue #6062

Updated by ipanova@redhat.com almost 5 years ago

If i generate a migration plan with some set of repositories, then one is removed in pulp2, and recreated with the same pulp_id. If i then re-run the exact same migration plan, pulp3 will error with this:

 If you have trouble re-creating the issue, i can try to nail down exact steps, but it should be something like: 

 

 1\. create a file repo in pulp2   
   
 2\. Run a migration plan like:   
   
 {   
   
 "plugins":\[   
   
 {   
   
 "type":"iso",   
   
 "repositories":\[   
   
 {   
   
 "name":"5b08c8a6-d3bb-41af-9cd4-cadf8fec2a55",   
   
 "repository_versions":\[   
   
 {   
   
 "pulp2_repository_id":"5b08c8a6-d3bb-41af-9cd4-cadf8fec2a55",   
   
 "pulp2_distributor_repository_ids":\[   
   
 "5b08c8a6-d3bb-41af-9cd4-cadf8fec2a55"   
   
 \]   
   
 }   
   
 \],   
   
 "pulp2_importer_repository_id":"5b08c8a6-d3bb-41af-9cd4-cadf8fec2a55"   
   
 }   
   
 \]   
   
 }   
   
 \]   
   
 } 

 

 3\. delete the repo in pulp2, recreate it with the exact same pulp_id for importers and distributors.   
   
 4\. re-run the migration plan
