Migration with a key '--allocate-only-required-resources' fails with an error:

└ Subscription ''
    ├ error: Failed to restore hosting settings of subscription with Plesk backup/restore.

Mail hosting were not created for this subscription.


  1. Connect to psa database:

    [root@server ~]# plesk db
  2. Check configured services for domain which failed to migrate:

    mysql> select * from DomainServices where dom_id in (select id from domains where name='');
    | id | dom_id | type | status | parameters_id | ipCollectionId |
    | 86 |     75 | web  |      0 |             0 |             86 |

From the output you can see that there is no mail hosting services is configured for the domain. Most likely because this resource is not used on the source subscription.

In such a case try to migrate without the key --allocate-only-required-resources.
