Migration Plugin

Note, that this was done on a fresh pulp3 db due to #6964

Here is my migration plan:

{
   "plugins":[
      {
         "type":"rpm",
         "repositories":[
            {
               "name":"pulp-uuid-rhel_6_x86_64",
               "repository_versions":[
                  {
                     "pulp2_repository_id":"pulp-uuid-rhel_6_x86_64",
                     "pulp2_distributor_repository_ids":[
                        "pulp-uuid-rhel_6_x86_64"
                     ]
                  }
               ],
               "pulp2_importer_repository_id":"pulp-uuid-rhel_6_x86_64"
            },
            {
               "name":"Published LIbrary view-355376805-405955044",
               "repository_versions":[
                  {
                     "pulp2_repository_id":"8_view1_archive",
                     "pulp2_distributor_repository_ids":[
                        "8_composite_version1",
                        "8_composite_version1_archive",
                        "8_view1",
                        "8_view1_archive"
                     ]
                  }
               ]
            }
         ]
      }
   ]
}

And here's the migrated repo versions:

pulpcore=# select * from core_repositoryversion;
               pulp_id                |         pulp_created          |       pulp_last_updated       | number | complete | base_version_id |            repository_id             
--------------------------------------+-------------------------------+-------------------------------+--------+----------+-----------------+--------------------------------------

This is basically what i would expect, since the first migrated repo has content and was migrated as (9d805f90-c152-40e7-a2ee-a3734745d0c3) version 1. The 2nd migrated repo was empty so it stays at version 0 (051d6557-35e5-4be0-8dda-ea8127bd99e9).

We can check version 1 and see that it has errata:

# curl  https://`hostname`/pulp/api/v3/repositories/rpm/rpm/9d805f90-c152-40e7-a2ee-a3734745d0c3/versions/1/  | jq

{
  "pulp_href": "/pulp/api/v3/repositories/rpm/rpm/9d805f90-c152-40e7-a2ee-a3734745d0c3/versions/1/",
  "pulp_created": "2020-06-11T18:04:09.435784Z",
  "number": 1,
  "base_version": null,
  "content_summary": {
    "added": {
      "rpm.advisory": {
        "count": 6,
        "href": "/pulp/api/v3/content/rpm/advisories/?repository_version_added=/pulp/api/v3/repositories/rpm/rpm/9d805f90-c152-40e7-a2ee-a3734745d0c3/versions/1/"
      },
SNIP

now lets check the migrated errata:

[root@devel2 ~]# curl  --cert /etc/pki/katello/certs/pulp-client.crt  --key /etc/pki/katello/private/pulp-client.key https://`hostname`/pulp/api/v3/pulp2content/ec697c30-c1e8-479a-b6b9-c28652343a86/ | jq


{
  "pulp_href": "/pulp/api/v3/pulp2content/ec697c30-c1e8-479a-b6b9-c28652343a86/",
  "pulp_created": "2020-06-11T18:04:07.072438Z",
  "pulp2_id": "7c084d6e-073e-4310-94e3-5ab06b66ef1e",
  "pulp2_content_type_id": "erratum",
  "pulp2_last_updated": 1591898638,
  "pulp2_storage_path": null,
  "downloaded": false,
  "pulp3_content": "/pulp/api/v3/content/rpm/advisories/b75d7ae7-f268-49d9-afaf-6e91bc7d8c7d/",
  "pulp3_repository_version": "/pulp/api/v3/repositories/rpm/rpm/051d6557-35e5-4be0-8dda-ea8127bd99e9/versions/1/"
}

Notice that the pulp3_repository_version is "/pulp/api/v3/repositories/rpm/rpm/051d6557-35e5-4be0-8dda-ea8127bd99e9/versions/1/" which doesn't even exist! It should be the only other repository that exists (/pulp/api/v3/repositories/rpm/rpm/9d805f90-c152-40e7-a2ee-a3734745d0c3/versions/1/)
