License Pooling

If the controller is paired with an availability partner, you can redistribute licenses when a Capacity Enhancement Key (AP or Radar) is installed. Both controllers must be running at least v9.01 and both members must have a permanent license key. Separate pools will be introduced for each type of license, and licenses installed on either member of an availability pair are shared across the pair automatically. License pooling is supported in fast failover and legacy availability setups. The limit of distribution is set by the license key; therefore if a controller has two keys of 25 APs each, then you will be allowed to transfer 25 or 50 APs to the former peer controller (for more information, see Availability).
