Migrating Data from PPP 9.0 and later to PPP 9.2
Backup and restore utilities provided by Parallels Plesk Panel 9.0 and later allow manual migrations using GUI and CLI.
In both cases, the data is first backed up on the source server and then restored at the destination.
To migrate from PPP 9.0 and later for Linux/Unix using CLI:
Create the server backup on a source server by running the command
# /usr/local/psa/bin/pleskbackup server –output-file=/dump.psa
Upload the created backup (dump.psa) to the destination server.
Restore the backup on the destination server:
Go to Home > Backup Manager
