Version Component Compatibility
When one license server manager manages multiple vendor daemons, it may be the case that those vendor daemons do not use the same version of FlexNet Publisher. By observing the FlexNet Publisher version compatibility rules described in Version Compatibility Between Components you are assured that all of your FlexNet Publisher components are compatible.
You can maintain multiple versions of FlexEnabled applications in the enterprise. The vendor daemon for an application must be at least the same version as the FlexNet Publisher version used in the FlexEnabled application.
