Installation and Upgrade
You can install CSO by using a GUI-based installer as well as through the CLI installer.
When you install or upgrade CSO by using the CLI, ensure that you save the passwords for each infrastructure component when they are displayed on the console because these passwords are encrypted and are not displayed again.
In addition, during the installation, ensure that you save the Administration Portal password that is displayed on the console. For the upgrade, you must log in using the password configured for the previously installed version of CSO.
If you are using the GUI installer, after the installation is successful, click the View all IP addresses and passwords link to view all the IP addresses used by CSO and the passwords for various CSO components.
Ensure that you save the passwords for each CSO component (the cspadmin password, used for the Administration Portal login, is the most important) because these passwords are not displayed again.

Software Installation Requirements for NFX Series Network Services Platform

- Upload the software image to CSO.
- Specify this image as the boot image when you configure activation data.

Upgrade Instructions
You can upgrade to CSO Release 4.1.0 only from CSO Release 4.0.2.
If your installed version of CSO is not Release 4.0.2, then you must perform a fresh installation of CSO Release 4.1.0.
If your installed version is CSO Release 4.0.2, you can use a script (upgrade.sh) to directly upgrade to CSO Release 4.1.0. If the upgrade is unsuccessful, you can roll back to CSO Release 4.0.2.
For more information, see Upgrading Contrail Service Orchestration Overview in the Installation and Upgrade Guide.
Installation and Upgrade Limitations
For SD-WAN deployments, CPE devices behind NAT are supported only for Internet links.
The VM on which the virtual route reflector (VRR) is installed supports only one management interface.
Post-Installation Instructions and Notes
Before you onboard devices, ensure that the device is running the software version that is recommended in this release notes.
To use full capabilities of CSO Release 4.1.0, we recommend that you upgrade the sites by using the site upgrade workflow, to Release 4.1.0.
After you upgrade a site, delete and recreate the SD-WAN policies other the ones that use local breakout. For local breakout policies, create a local breakout profile.
After you upgrade CSO to Release 4.1.0, existing SD-WAN policies are shown as undeployed in the CSO UI even though the policies are still active and deployed.
