I intend to move an existing 10.13 installation to a new host running v16. I have full backups from the 10.13 created daily through FreePBX. I have downloaded SNG7-PBX16-64bit-2204-1.iso and will dd this to a flash drive.
My question is: Once 16 is installed on the new host is the transfer as simple s copying the full backup file from the 13 host and restoring it through FreePBX on the 16 host? Or is more required? If so then what?
