Why 'is not possible to upgrade the software of this system Info file to a newer version' in BVMS?
The validity of the SMA date should cover the BVMS version release date you wish to upgrade to. Otherwise, the upgrade will not work and you will get the message "It is not possible to upgrade the software of this System Info file to a newer version".
In case the software assurance has expired, order an SMA expansion for your system.
You can check the software assurance status of your BVMS in your Remote Portal Account (Software Licensing > 3 dots button > Assurance Report) → How to check the Software Maintenance Agreement (SMA) status of BVMS 11.x via Remote Portal?
Also, please note that this message could occur in case you are trying to upgrade your BVMS and it is on the latest available version released.
