Domain was migrated from Parallels Plesk Panel on FreeBSD to Parallels Plesk Panel version 10. Plesk Migration Manager But domain content was not migrated. Default Plesk page is displayed instead of the domain content.
In version 10 Plesk Migration Manager packs the domain content using call of the 'tar' command via the 'su' command with the '--shell' parameter under FTP user credentials.
'su ftpuser --shell /usr/local/bin/bash -c "/usr/bin/tar -f - -c -X '/var/tmp/tmp.2.U0n7pk' *"' in /home/vhosts/domain.tld/httpdocs
However, the 'su' command in FreeBSD does not understand '--shell' paramter and the 'tar' command cannot be executed.
This problem was discovered in Parallels Plesk Panel version 10.0.1.
It can be fixed by applying hotfix on the target server.
