    plesk db "DELETE FROM TmplData WHERE element='php_handler_type'"

  4. Log in to Plesk on the target server.

  5. Go to Tools & Settings > Migration & Transfer Manager > 203.0.113.2

  6. Click the button Reload source data and re-migrate necessary subscriptions.

  2. Create Plesk database backup

  3. Run the following two commands to remove all unnecessary lines from Plesk database:

    # plesk db "DELETE FROM TmplData WHERE element='php_version'"

    # plesk db "DELETE FROM TmplData WHERE element='php_handler_type'"

  4. Log in to Plesk on the target server.

  5. Go to Tools & Settings > Migration & Transfer Manager > 203.0.113.2
