When trying to upgrade a SmartX server from 3.0.x.x to any hotfix build, you get the following errors:
EcoStruxure Building Operation
- Building Operation Automation Server
- Building Operation Device Administrator
This is an issue within 7z. The path becomes too long on the unzipping of it. In 3.1 and onwards, only the GUID is used as the folder name. In 3.0, its is the file name + GUID which causes the path to become too long.
Rename the firmware file so that it is shorter in length.
