Plan the Software Upgrade
Before you upgrade the software version, prepare the NCS 1020 to ensure that the upgrade process is seamless.
This section describes the following processes to prepare your NCS 1020 for an upgrade:
Backup Current Configuration
The ability to recover from a disaster is an essential part of any system maintenance plan. We recommend you backup the configurations in a secure remote location and verify that the transfer is a success, both before and after upgrade.
Procedure
Step 1 |
Create a backup of the running configuration to one of the following locations based on your requirement:
|
Step 2 |
Verify that the configuration is backed up. |
Check System Stability
System stability checks are essential to measure the efficiency and ability of an upgrade to function over an extended period.
At the EXEC prompt, execute the following commands to assess basic system stability checks before and after the software upgrade.

Obtain Install Files
You can obtain the install files based on one of the following options that is best suited to your network:
-
Base ISO and Optional RPMs: You can upgrade the software through the standard method where you install the ISO followed by the required RPMs.
-
Golden ISO: You can build a customized golden ISO (GISO) image with the base ISO and the required RPMs to automatically upgrade the software.
Standard ISO and RPMs
Note |
Contact your Cisco Systems technical support representative for NCS1020 ISO image with required IOS-XR version and optional RPM's. |
Golden ISO
Note |
Contact your Cisco Systems technical support representative for NCS1020 Golden GIOS image creation with required IOS-XR version and optional RPM's information. |
Create Repository to Access Install Files
A Repository is a directory where the ISO, RPMs, and their metadata are downloaded. The package manager uses this repository to query the packages.
The repository can either be created locally on the NCS 1020, or on a remote location that can be accessed through FTP, HTTP, or HTTPS. In a repository, you can create directories based on different Cisco IOS XR platforms, releases or both. You can create and use multiple repositories. The files to be installed can saved in the local repository, remote repository or a combination of both.
Note |
The Golden ISO (GISO) method does not require you to create a repository. However, you can still install the GISO from a remote repository. |
Important |
Each package is named based on its name, version, software release, and architecture. Hence, any packages that have these attributes in common and differ only by platform are indistinguishable. We recommend that you create different repositories for different platforms and releases. |
