Licensing Updates
Software Subscription Cancelation
- End-User License-Subscription Agrement changes are summarized in the below section extracted from Neverfail End-User Software Subscription License Agreement.

Automatic Software Subscription Cancelation. Neverfail reserves the right to automatically cancel any Software Subscription if the Subscriber does not pay for either a monthly or a yearly subscription renewal for it within maximum 6 months past the Software Subscription’s end date. A Canceled Software Subscription is considered end of life, hence will not allow to be reactivated, renewed, or extended. If the subscriber will later want to continue the software usage, a new Software Subscription must be purchased to re-enable the subscriber with the Right of Use for the Licensed Software.
Software Subscription Payment Awareness Improvements
- Improved in v15.0, the software subscription licensing mechanism is changed to be aware of software subscription's payment status. The changes are summarized in the below section extracted from Neverfail End-User Software Subscription License Agreement.
Term Software Subscription is ready to be consumed immediately upon fulfilment. Depending on the payment status, the right to use may or may not be limited a follows: (a) if the payment is pending when software subscription is being activated (consumed), a limited forty-five (45) days license key counted from the term software subscription start date will be generated; as soon as the payment is confirmed, the full term software subscription period is unlocked; relicensing with a full term license key will be performed automatically for online licensing; (b) if the payment is confirmed when software subscription is being activated (consumed) a full term license key will be generated. Similar payment status usability rules apply also in the case of license term software subscription renewal.- v15.0 licensing model is built on top of v9.0 model which transitioned Engine from a perpetual model to a software subscription term and rental model. Engine Licensing Service (ELS) enables call-home features that power our software subscription based licensing. The new cloud service is free but is required for Term and Rental deployments. For more information on how the licensing works and upgrade notes please read Continuity Engine Licensing Model.
Backward Compatibility
Continuity Engine 15 Management Service is compatible with older versions (i.e. EMS 15.0 manages correctly CE 9/10/11/12/13/14).
- If I upgrade to Continuity Engine 15, will my perpetual license cease? Yes! You are accepting software subscription's requirements outlined in the new EULA for Term and Rental. Neverfail will generate new software subscriptions expiring the same day as the support was paid through. This means you will need to pay for support to continue software operations yearly or monthly depending on the type of subscription.
- Can I upgrade using the Upgrade Wizard from older versions to Continuity Engine 15? Yes, the upgrade wizard is still supported. Keep in mind that Continuity Engine 6.7, 7.x, 8.x and 9.x are currently End-of-Life (EOL). To ensure organization continued support, you must upgrade to the latest Continuity Engine version.
When will Continuity Engine EOL? Check End of Life Policy for Neverfail Continuity Engine
Can I stay on previous versions of Continuity Engine? Yes, however, previous versions will eventually EOL and you will not be able to take full advantage of the new features of Continuity Engine v14. And evenly important, your systems will be more exposed to cyberattacks. For example:

- CEv10.0

- misses all the security fixes between April 2023 (Tomcat 9.0.74) and July 2024 (9.0.91).
