Requirements for Virtual Appliance Version 135.0.0
Upgrading to version 135.0.0
Before downloading the upgrade package, ensure the following:
- You are running a minimum version of 128.0.0. If you are running appliance versions older than 128.0.0, 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.
Note
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 42 GB of free space on the
/opt/ns/upgradespartition where the upgrade package is downloaded. You can delete older versions of the appliance from theupgradesfolder 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 cz.archive.ubuntu.com port 80 Executing telnet as: ['telnet', 'cz.archive.ubuntu.com', '80'] Trying 217.31.202.63... Connected to mirror-r-01.nic.cz. Escape character is '^]'.
The following are the minimum hardware requirements to install and run the Virtual Appliance.
| Component | Requirements |
|---|---|
| Physical RAM | 32 GB |
| Processor | 8-Core |
| Hard disk space | 450 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. Note 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.X where the Xs represent the major, minor, hotfix, and build release numbers, respectively. For example, appliance release 110.0.0 and older releases are deprecated when appliance release 135.0.0 goes live. Release numbers are not sequential like 101, 102, and 103. Instead, release numbers jump numerically, like 128.0.0, 132.0.1 and 135.0.0, to reflect parity with the Netskope Cloud Releases.
The following table provides the upgrade path to the latest software version.
| Current version | Upgrade to version |
|---|---|
| Any version before 128.0.0 | 128.0.0 |
| 128.0.0 | 135.0.0 |
| 132.0.1 | 135.0.0 |
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.
