When migrating entitlement keys from HM on premise to HMNG I get following error:
License Server Error: The dates specified in this entitlement key are invalid
Though my keys are still valid until next year.
If you PM me I can send you the keys,
Since on-prem uses perpetual licensing and NG (cloud) is subscription based, we had to up our licenses.
