Requirements for Virtual Appliance Version

Upgrading to version

Before downloading the upgrade package, ensure the following:

  • Rollback from is not supported.
  • You are running a minimum version of 96.0.0. If you are running appliance versions older than 96.0.0, or if the root (/) partition is less than 64 GB, you must deploy a new Virtual Appliance and import configurations from the old appliance. To learn more: Install a Virtual Appliance.


    If your Virtual Appliance uses a 64 GB root (/) partition, then you must ensure that at least 8 GB of free space is available before upgrading.

  • There is at least 25 GB of free space on the /opt/ns/upgrades partition where the upgrade package is downloaded. You can delete older versions of the appliance from the upgrades folder to free up disk space.

    To learn more: Upgrade the Virtual Appliance.

  • All the dhcp interfaces on the appliance are configured with a static IP, netmask and gateway.
  • Export the current appliance configurations to a different host. To learn more: Exporting Configurations.
  • To verify that the host is reachable, run the following telnet command.
    nsappliance> telnet host port 80
    Executing telnet as: ['telnet', '', '80']
    Connected to
    Escape character is '^]'.

The following are the minimum hardware requirements to install and run the Virtual Appliance.

Physical RAM32 GB
Hard disk space400 GB is the total disk space required across all partitions. This includes 96 GB for storing and processing logs and 304 GB for the root partitions which store the Netskope software, configuration files, and data files.

You must increase the disk capacity depending on the size of the logs that are processed daily.

For information on increasing the partition size, see “Increase the Size of the Partition” under Optional Configurations topic on the Knowledge Portal.


Netskope recommends that you increase the disk capacity by 5 times the expected daily log collection size.

Appliance Software Version Support

Netskope Appliance software releases are available every 4-months and will have Netskope support up to two previous versions. Direct software upgrades are supported as long as the “from” and “to” software releases are within two versions apart.

Netskope appliance releases are numbered in the form of X.X.X where the Xs represent the major, minor, and build release numbers, respectively. For example, appliance release 93.1.0 and older releases are deprecated when appliance release goes live. Release numbers are not sequential like 101, 102, and 103. Instead, release numbers jump numerically, like 96.0.0, 99.0.0, and, to reflect parity with the Netskope Cloud Releases.

The following table provides the upgrade path to the latest software version.


If you configured the appliance to act as a DPoP appliance and manually deleted the URL database package, you must first disable DPoP before you install the upgrade. Use the following command to disable DPoP:

set dataplane forward-proxy enable false

Once you install the upgrade, use the following command to re-enable DPoP:

set dataplane forward-proxy enable true

Current versionUpgrade to version
Any version before

Releases that are outside the Netskope support period:

  • Are not guaranteed to work with the latest cloud releases.
  • Are no longer tested by Netskope.
  • Do not receive hotfixes.
  • Do not receive new feature updates.

At our discretion, we may provide support for releases outside our support period. If a customer encounters an error in a version of software that is other than the latest release, Netskope may require the customer to upgrade to a specified later version to obtain a correction of the error.

For information about end-of-life and end-of-support for appliance releases, refer to EOL/EOS for DPoP r99.
