Upgrade NSX to 4.x- do hosts need to be rebooted?

  • 1.  Upgrade NSX to 4.x- do hosts need to be rebooted?

    Posted Jul 02, 2025 12:11 AM

    We are currently using NSXT v3.2.4.0.0.23653566 and will be upgrading to NSXT 4.2.2.1 and I have read the release notes (Upgrade Guide) and I'm still confused as to whether the hosts need to be rebooted after being upgraded?

    I believe the process is:

    • Upgrade the controllers.
    • Upgrade the hosts.
    • Upgrade the edges

    Is this correct?

    Yes the upgrade order of the components you listed is correct. Also by default post the upgrade,hosts will not ask for reboot unless you have manually set any host group settings to reboot after the upgrade. 

    In case of the DRS recommendations being logged, user will have to manually migrate VMs out of the host, before the host getting upgraded.
