It is not possible to migrate duplicate MX records with different priorities.
This is Plesk Migrator bug PMT-4556, which will be fixed in future updates.
As a workaround recreate MX records which are missing on the target server with following steps:
- Login to Plesk
- Navigate to Domains > example.com > DNS Settings
- Click Add Record.
- Select Record type MX and fill in the required information.
