6 Upgrading Mellanox WinOF Driver
The upgrade process differs between various Operating Systems.
• Windows Server 2008 R2:
When upgrading from WinOF version 3.2.0 to version 4.40 and above, the MLNX_WinOF driver
upgrades the driver automatically by uninstalling the previous version and installing the new driver.
The existing configuration files are not saved upon driver upgrade.
• Windows Server 2012 and above:
• When upgrading from WinOF version 4.2 to version 4.40 and above, the MLNX_WinOF
driver does not completely uninstall the previous version, but rather upgrades only the
components that require upgrade. The network configuration is saved upon driver
upgrade.
• When upgrading from Inbox or any other version, the network configuration is automati-
cally saved upon driver upgrade.
