    -====== Preparing the update ====== 
    -{{indexmenu_n>2}} 
    -This upgrade includes new network cards' drivers. This operation may require reboot. 
      
    -If your computer's network cards do not support Bypass functionality, we advise to switch to a reserved channel during upgrade. Please check  [[en:dpi:update:previous:ver_1_0:dpi_10_fix:dpi_10_faq_min|How to reduce down time to 10 s]] in case this is not possible. 
    - 
    -Bypass cards owners can safely perform upgrade, reboot the computer and even switch the power off. The traffic would be bypassed through "bypass" interface during maintenance. 
    -  
    -We advise to upgrade OS at the same time as the platform. 
    - 
    -Please keep at hand the following information before you start the upgrade: 
    -  - The number of network DNA interfaces' pairs used by DPI:<code>grep -E "^(in|out)_dev" /etc/dpi/fastdpi.conf</code> 
    -  - The type of DNA network card: igb or ixgbe and its capacity: 1G or 10G <code>ethtool -i dna0|grep driver 
    -ethtool dna0|grep Speed</code>Here dna0 is to be replaced by interfaces from item 1. 
    -  - Are the types of drivers for control interface and DNA interface the same?<code>ethtool -i eth0|grep driver</code>Here eth0 is to be replaced by the interface name in use (the list can be collected by ipconfig instruction). 
    -  - Is bypass mode supported by your network card? :!: Bypass cards owners: please do not upgrade the OS kernel! The manual will be updated to describe this case.
