The user ran "content migration-stats states" at the beginning of migration, and was given an estimate of 4 hours and 14 minutes:

  1. foreman-maintain content migration-stats
    Running Retrieve Pulp 2 to Pulp 3 migration statistics ================================================================================
    Retrieve Pulp 2 to Pulp 3 migration statistics:
    ============Migration Summary================
    Migrated/Total RPMs: 0/236788
    Migrated/Total errata: 0/332368
    Migrated/Total repositories: 0/540

Estimated migration time based on yum content: 4 hours, 14 minutes

Note: ensure there is sufficient storage space for /var/lib/pulp/published to double in size before starting the migration process.
Check the size of /var/lib/pulp/published with 'du -sh /var/lib/pulp/published/'

The actual migration time was more than 14 hours.

Version-Release number of selected component (if applicable):

Katello 3.18

Actual results:

migration took more than 14 hours

Expected results:

migration time should have been close to the estimate of 4 hours and 14 minutes
