Last time when I migrated my ISPConfig 3.0548 system to a new machine, the procedure of restoring the client's db and web site simply does not work. Firstly, I moved all the files under /var/backup/ from the old system to the new system. Then, I logged into my own client account and then pressed the 2 Restore buttons (picture). It was just saying the process was going. Then, I checked the DB and web site from the OS level, they actually were not created. What is the correct procedure to restore a client's own DB and web site from his own client level privilege? My system is ISPConfig 3.0548, Ubuntu 14.04, php 5.5.9, MySQL 5.5.46, Apache 2.4.7.
