Support and Update Service

What is the Support and Update Service (SUS)?

Last Updated: Apr 28, 2017 03:47PM UTC

Support and Update Service (SUS) is the software maintenance program which entitles customers to technical support and allows customers to perform a major version upgrade to a newer version free of charge.

SUS applies to Virtuozzo, Virtuozzo Storage and Virtuozzo Containers.

SUS for Lease licenses (that are paid for on a monthly or yearly basis) does not have expiration date; it is valid while the license is valid.

SUS for Perpetual/Purchased* licenses (that are 1 time purchases) is activated for one year with the initial purchase and can be renewed before the first year purchase anniversary date for 20% of the base retail price of your license key(s).

If the SUS on your license has expired and you want to upgrade to a newer version of Virtuozzo you have the option to reinstate the SUS on a key for 50% of the original retail price for that key.
