Issue Trying to upload a backup from 18.0.52.3 to a machine running 18.0.54 Update #1

[modusmongo]

Hello. My Ubuntu machine running 18.0.52.3 has effectively died. I do, however, have the backups from the /var/lib/psa/dumps directory on my local machine.

However, my new machine running 18.0.54 Update #1 refuses to upload any of my backup files. Error message :

Error: Unable to upload mysql.daily.dump.0.gz to the server storage: Unable to import file as dump: Import error: Unable to find archive metadata. The archive is not valid Plesk backup or has been created in an unsupported Plesk version

Is there any way around this?

Can I install 18.0.52.3 on the new machine, do the uploads, then upgrade Plesk to the current version?

Thanks!
