It is now in the release notes of the firmware Build 66.59 | NSHELP-42818 This issue will impact you if you have an SDX migrated or migrating from any type of NetScaler local license (fixed capacity subscription or perpetual license) file based licensing to any type of license with LAS based licensing and the legacy file-based licenses have not been deleted from the SVM. Impact: If there is any local legacy file-based license yet existing on the SVM after having transitioned to LAS, then the expiry of the file-based license triggers the un-licensing of the SDX (SVM and VPX on SDX) on the date of that license file expiry. Workaround: Delete the local file-based license(s) on the SVM after the migration to LAS has been done successfully. The file-based licenses would be located in SVM folder /mpsconfig/license and must be deleted from this folder using the shell prompt.

13.1 thread impacted as well?

Have not seen, but I’d assume yes.

Thanks for the call out here and on LinkedIn Richard!

I'm glad I did that initially 🙂

Community article now. Good thing, on the 16th....

Day late... dollar short comes to mind

Seems to be their mantra....

got "some" emails on this 😄

So is the Z license from Flex deployments included in this? Or just the locally licensed versions.

All local .lic licenses from what I understand.
