VIOSO releases frequently updates for all products. From activation date, every license is authorized to get updates to newer software versions for 3 months. After this period you can renew your license to receive updates again. Your last eligible update will always continue working.
VIOSO Servers include 2 years of maintenance for preinstalled VIOSO applications.
The end of such update subscription is called the maintenance expiry date of a license. When this maintenance expiry date is reached, a license will not work for newer software versions. The license is still valid without limitations for older software versions.
Every license can be upgraded with a 1-year maintenance renewal at all time (even if the maintenance renewal date has already expired).
