Issue
In the process of upgrading a Niagara G3 ENC from version 3.0 to version 3.1, the station fails to start due to an invalid license.
Environment
Niagara G3 ENC
Cause
In order to complete an upgrade to version 3.1, it is necessary to obtain a 3.1 license.
Resolution
Ensure that a new license is available to install in the ENC before upgrading. Once the ENC has been upgraded it cannot be downgraded back to 3.0 unless it is done by the factory. If a new 3.1 license has not been installed, the ENC will be inoperable until it is installed.
