Does the mapping between license activation codes and device ESNs need to be considered when the AR router has multiple license activation codes

Different AR models of the same series (such as AR1220V and AR1220W) obtain license files using activation codes and ESNs, there is no need to consider the mapping activation codes and ESNs.
When AR routers of different series (such as AR1220, AR2240, and AR2240C) obtain license files using activation codes and ESNs. The activation codes are applicable to the series only.

Note:
Note uppercase and lowercase letters of ESNs when applying for a license. If the ESN in the license file is different from that on the AR router, the license may fail to be activated.
