Hi ,

You should get the MD5 value.

Once u go to Software Installation/Upgrade, select the iso patch and in Download Status, u would get message Checksumming the file followed by Screen showing MD5 value,version info and Switch version option.

Please check.

Hi.

If it lets you to install, go ahead without issue.

On release 10.x you will need to apply a cop file to support newer MD5.

We are upgrading CUCM 9.1 to latest version, download file size is right.

In the CUCM software upgrade process, I am able to see the upgrade ISO files, but MD5 value is missing, please let me know do we have any risk in this upgrade, please advice.

Pior to uploading iso, u can verify the checksum using any MD5 checksum utility and compare with MD5 available on cisco site.

But I have never seen like this.
