Cisco NFVIS upgrade
A Cisco NFVIS upgrade is a software update process that
-
requires copying the upgrade image to the server before starting the process, and
-
ensures cryptographic integrity and authenticity through signed RPM packages.
-
shuts down the VM and retains VM data during the upgrade, and after the upgrade automatically restores the VM to its prior operational state upon completion.
Upgrade image formats and security
The Cisco NFVIS upgrade image is available as a .iso file. All RPM packages in the Cisco NFVIS upgrade image are signed to ensure cryptographic integrity and authenticity. In addition, all RPM packages are verified during Cisco NFVIS upgrade.
![]() Note |
Currently, downgrade is not supported. |
Image copy requirements
Ensure that you copy the image to the Cisco NFVIS server before starting the upgrade process. Always specify the exact path of the image when registering the image. Use the scp command to copy the upgrade image from a remote server to your Cisco NFVIS server. When using the scp command, you must copy the image to the "/data/intdatastore/uploads" folder on the Cisco NFVIS server.

Upgrade using ISO file
This task enables you to upgrade Cisco NFVIS using an ISO file through command line operations or portal interface.
You can upgrade the system by copying the upgrade image using SCP commands or by uploading through the Cisco NFVIS portal. The upgrade process involves registering the image and then applying the upgrade.
Procedure
|
Step 1 |
Copy the upgrade image using one of the following methods:
|
||
|
Step 2 |
Register the image using the system upgrade image-name command. |
||
|
Step 3 |
Upgrade the image using the system upgrade apply-image command. |
The system upgrade process completes successfully with the new ISO image installed and operational.
Register an image
Register an image in the system to prepare it for upgrade operations.
Image registration is a prerequisite step before applying system upgrades. This process registers the image file in the system's upgrade directory and validates its integrity.
Procedure
|
Step 1 |
Register the image using the system upgrade command. Example:
|
||
|
Step 2 |
Verify the image registration status. Example:
|
The image is successfully registered in the system and shows a "Valid" status, indicating it is ready for upgrade operations.
Upgrade the registered image
This task applies a registered image upgrade to the system at a scheduled time.
Use this procedure when you need to upgrade the system software to a newer version using a previously registered image.
Procedure
