This section describes the known issue that may occur during the upgrade of the StarOS image.
Install and Upgrade Notes
This Release Note does not contain general installation and upgrade instructions. Refer to the existing installation documentation for specific installation and upgrade considerations.
When upgrading the StarOS image from a previous version to the latest version, issues may arise if there is a problem with the Cisco SSH/SSL upgrade. To avoid such issues, ensure that the boot file for Service Function (SF) cards is properly synchronized.
To synchronize the boot file for all the Service Function (SF) VPC-DI non-management cards, use the following CLI command:
[local] host_name# system synchronize boot
This ensures that the changes in boot file are identically maintained across the SF cards.
Note: Execute the system synchronize boot command before reloading for version upgrade from any version earlier than 21.28.mh14 to version 21.28.mh14 or versions higher than 21.28.mh14.
Upgrade the confd version
This section explains upgrading third-party software. Upgrade the confd software to ensure system compatibility and performance.
Note: During July 2025.03.0 release, confd is upgraded to 8.1.16.2 version.
Prerequisites:
● Ensureyouhaveappropriatepermissionstoperformthisupgrade.
● Backupallnecessarydataandconfigurationstoavoidpermanentlossduringfiledeletion.
Perform these steps to upgrade the confd version on the system.
1. Enter the debug shell using debug shell command.
2. Navigate to the confd directory.
3. Run the command:cd /mnt/hd-raid/meta/confd/ to access the directory.
4. Remove existing files with the command; rm -rf *
All files and subdirectories are deleted, preparing the system for a fresh installation. To preserve data across the Method of Procedure, users with ConfD configured must contact their Cisco representative.
Method of Procedure (MOP): Upgrade/Downgrade Between Non-Hermes and Hermes Builds
CSCwr80301: HD-RAID Not Ready During Upgrade from Non-Hermes to Hermes
Issue: When upgrading from a non-Hermes (202x.0x.gx) to a Hermes (202x.0x.ghx) build on both Virtualized Packet Core—Distributed Instance (VPC-DI) and Virtualized Packet Core—Single Instance (VPC-SI) platforms, the HD-RAID may not come up as expected.
Workaround: To avoid this hd-raid failure, follow the steps below during the upgrade and downgrade (for example, from 2025.03.g0 to 2025.04.gh0):
1. Pre-requisite: Back up all files stored in /hd-raid before upgrading from the .mx to .mhx build.
Note: All data in /hd-raid will be lost during recovery.
2. Before the upgrade: On the .mx build, run the hd raid clear command.
3. Reboot and upgrade: Reboot the node to upgrade to the .mhx build.
4. Perform the CF card migration in case of VPC-DI or Reload the chassis on VPC-SI. Wait for the HD-RAID to recover.
Note: It is recommended to use this Method of Procedure (MOP) for both upgrading and downgrading between Hermes and Non-Hermes StarOS builds.

StarOS product version numbering system
The output of the show version command displays detailed information about the version of StarOS currently running on the ASR 5500 or Cisco Virtualized Packet Core platform.
Starting 2024.01.0 release (January 2024), Cisco is transitioning to a new release versioning scheme. The release version is based on the current year and product. Refer to the figure for more details.
Note: During the transition phase, some file names will reflect the new versioning whereas others will refer to the 21.28.x- based naming convention. With the next release, StarOS-related packages will be completely migrated to the new versioning scheme.
Note: For any clarification, contact your Cisco account representative.
Software integrity verification
To verify the integrity of the software image you have from Cisco, you can validate the SHA512 checksum information against the checksum identified by Cisco for the software. Image checksum information is available through Cisco.com Software Download details. Click Linux and then choose the Software Image Release Version.
To find the checksum, hover the mouse pointer over the software image you have downloaded. At the bottom you find the SHA512 checksum, if you do not see the whole checksum, you can expand it by pressing the "..." at the end.
To validate the information, calculate a SHA512 checksum using the information in the table and verify that it matches the one provided on the software download page. To calculate a SHA512 checksum on your local desktop see the table.
Table 8. Checksum calculations per operating system
| Operating system |
SHA512 checksum calculation command examples |
| Microsoft Windows |
Open a command line window and type the following command: > certutil.exe -hashfile <filename>.<extension> SHA512 |
| Apple MAC |
Open a terminal window and type the following command: $ shasum -a 512 filename.extension |
| Linux |
Open a terminal window and type the following command: $ sha512sum filename.extension OR $ shasum -a 512 filename.extension |
| Note: filename is the name of the file. extension is the file extension (for example, .zip or .tgz). |
|
If the SHA512 checksum matches, you can be sure that no one has tampered with the software image or the image has not been corrupted during download.
If the SHA512 checksum does not match, we advise you to not attempt upgrading any systems with the corrupted software image. Download the software again and verify the SHA512 checksum again. If there is a constant mismatch, please open a case with the Cisco Technical Assistance Center.
Certificate validation
In 2024.01 and later releases, software images for StarOS, VPC-DI, and VPC-SI, and the companion software packages for StarOS and VPC are signed via x509 certificates. USP ISO images are signed with a GPG key. For more information and instructions on how to validate the certificates, refer to the README file available with the respective software packages.
