In #1902 said the following:

PR was reverted due to high amount of DB load on data migrations.
Set on hold until Sidekiq will be online in prod so we could implement the PR in question in two parts:

    Preparing the DB via async jobs
    Updating code itself.

Therefore, all the fields that were created in the #1902 case disappeared and the ticket with the preservation of domains after unlocking becomes relevant.
Since we have had changes in the structures of the project, the plan is as follows:

1. This PR will have to go to the master FIRST! because it prepares the structure for data migration.
2. The second step will be to create a rake task (this will be a separate PR), which will migrate data to a new database structure
3. But the third step and the third PR will decide the question of how to maintain the necessary statuses
