We are looking to upgrade from Plesk 8.3 to Plesk 9, but want to do so without any problems. From reading these threads, it seems the autoupdater is rather buggy and we would rather not risk an unsuccessful upgrade. What is the best bet to upgrade? Should we go from Plesk 8.3 to 8.4, then 8.4 to 8.6, and 8.6 to 9? Or is it safe to go straight from Plesk 8.3 to 9? Any comments or suggestions welcome.
