Transition to subscription-based licensing and key enforcement

Last published : Sep 22, 2026
InfoScale is discontinuing the use of perpetual and keyless licenses. Key changes include:
  • New license format: Permanent keys are replaced by a universal term-based license that aligns directly with the end-date of your subscription entitlement. The .slf license key format is replaced by the .lic format, introducing a single cross-platform license key. Keyless license type is deprecated.
  • Active lifecycle enforcement: Unlike previous versions, where license expiration only triggered system log notifications and product functionality continued indefinitely, the new model actively enforces the license lifecycle.
  • Enforcement phases: To prevent sudden service disruptions while ensuring compliance, expired licenses transition through three distinct states: Warning, Grace, and Enforcement with product functionality impacted in the enforcement phase.
For more details about the subscription-based licenses and their enforcement, refer to the InfoScale 9.2.0 Installation and Upgrade Guide.
