User`s guide

It is recommended that you do the following before starting the upgrade:
• Install all Parallels updates available for your system.
• Back up all Containers and virtual machines on the server.
• Perform a full backup of the entire server using a third-party software. For example, you can
make use of the Acronis Backup & Recovery 10 Advanced Server (a free trial version is available
at http://www.acronis.com/backup-recovery/advanced-server) software allowing you to quickly
create an exact copy of your server and to easily restore the entire system if something goes
wrong during the upgrade.
