Upgrading from SWsoft Virtuozzo 3.0 Service Pack 1 8

Preparing for the Upgrade

Follow the below steps to prepare for the upgrade procedure:

1 Carefully read the information given in the Known Issues and Restrictions section (p. 12).

This will help you avoid possible problems related to the upgrade and successfully solve any

problems that may appear.

2 Check if the license installed on the Hardware Node can be upgraded to support Parallels

Virtuozzo Containers 4.6. Parallels Virtuozzo Containers 4.6 does not support the old

licensing format; so you need to upgrade the license to use it with Parallels Virtuozzo

Containers 4.6. To check if your license is upgradeable, follow the

https://register.parallels.com/vz_key_maintenance link, enter the license key number and the

email you used when purchasing the license in the respective fields, and click the Check

Maintenance button. The system will inform you if the license can be automatically

upgraded.

Note: If your license cannot be upgraded automatically, see the Upgrading Licenses Manually

section below to learn how to upgrade licenses manually.

3 Obtain the Parallels Virtuozzo Containers 4.6 distribution set. Download the vzinstall-

linux-i386.bin or vzinstall-linux-x86_64 utility (for the x86 or x86-64

version of Parallels Virtuozzo Containers 4.6, respectively) from the Parallels web site. You

can then use these utilities to download Parallels Virtuozzo Containers 4.6 to your server

and install it there.

4 As with any major changes to the hard disk, it is recommended that you do the following

before starting the upgrade:

 Back up all Virtual Environments on the Hardware Node.

 Perform a full backup of the entire Virtuozzo server using a third-party software. For

example, you can make use of the Acronis

True Image Echo™ Enterprise Server (a

free trial version is available at

http://www.acronis.com/enterprise/download/ATIESWin/) 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.
