Upgrading from SWsoft Virtuozzo 3.0 Service Pack 1 10
Upgrading Virtuozzo Software
To upgrade your system to Parallels Virtuozzo Containers 4.6, do the following:
1 Download the vzinstall-linux-i386.bin or vzinstall-linux-
x86_64.bin utility (for the x86 or x86-64 version of Parallels Virtuozzo Containers 4.6,
respectively) from the Parallels web site.
The process of downloading and installing Parallels Virtuozzo Containers 4.6 with the
vzinstall-linux-i386.bin and vzinstall-linux-x86_64.bin utilities is
the same. Therefore, we use a generic term vzinstall-linux.bin to indicate both
utilities throughout this document.
2 Run the chmod a+x vzinstall-linux.bin command to make the vzinstall-
linux.bin utility executable.
3 Execute the vzinstall-linux.bin utility. You can run vzinstall-linux.bin in
one of the following modes:
 In the 'Download and install' mode, the utility automatically starts the upgrade after it
has downloaded the Parallels Virtuozzo Containers 4.6 installation files to the server.
 In the 'Download only' mode, the utility only downloads the Parallels Virtuozzo
Containers 4.6 installation files but does not install them on the server. You can copy the
downloaded files to the server you plan to upgrade to Parallels Virtuozzo Containers 4.6
and execute the following command:
# ./virtuozzo-4.6.0-<build_version>-<arch>.sfx
Detailed information on the vzinstall-linux.bin utility is provided in the Parallels
Virtuozzo Containers 4.6 Installation Guide.
During the upgrade, you will have to complete the same steps as those described in the Parallels
Virtuozzo Containers 4.6 Installation Guide for installing Parallels Virtuozzo Containers 4.6 on
a fresh Linux distribution, except for the step where you are asked to upgrade your current
license. When deciding on whether to upgrade the license, keep in mind the following:
 You must have an active Internet connection for the license upgrade to complete.
 You can decline the license upgrade and enter the upgraded license later. Consult the
previous section for the information on how to manually upgrade licenses.
 If you decline to upgrade the license or your license is non-upgradeable, you will be
prompted to enter a valid Parallels Virtuozzo Containers 4.6 license during the upgrade
procedure.
 Once your license is upgraded, you will not be able to auto-return to the old licensing
format. If, however, you decide to downgrade to one of the previous versions of Parallels
Virtuozzo Containers, contact the Parallels support team.
