Conditions
To use license migration feature, the following conditions should be met:
• Same Nebula Device owner and product tier: Both USG FLEX or ATP Series and USG FLEX H Series must belong to the same Zyxel Account owner and Nebula Device tier (for example, USG FLEX 500 to USG FLEX 500H).
The following table describes the supported Nebula Firewalls license migration mapping at the time of writing.
