We are attempting to restore a backup from an existing self-hosted 3CX v20 Update 8 instance that uses a custom FQDN to a new 3CX-hosted deployment.
However, when we upload the backup file through the 3CX portal, the upload fails with an "Invalid FQDN" error.
Steps performed:
b.xml file within the backup needs to be modified to include a new FQDN and license key before the restore?
If so, what should be specified for the FQDN, considering that the system will be hosted by 3CX and we understand that a new FQDN will be assigned during the hosting process?
Any guidance on the correct migration procedure would be appreciated.

Steps performed:
- Created a full backup of the existing 3CX PBX.
- Unlinked the existing FQDN from the 3CX portal.
- Started the process of converting the system to a hosted deployment.
- Attempted to upload the BACKUP.ZIP file during the restore process.
- Received an "Invalid FQDN" error when uploading the backup.
