Transition to subscription-based licensing and key enforcement

Last published : Sep 23, 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 9.2.2 Installation Guide.
Please note that you may still encounter legacy references to perpetual and keyless licenses in the current documentation while documentation updates are underway. You can ignore these outdated references.
