CUCM 11.0 to 11.5 Upgrade

[Mark Dragone]

Hi All - I am trying to upgrade CUCM from 11.0 to 11.5 and am running into an issue.  The MD5 and SHA512 checksum from the website does not match the MD5 and SHA512 after the download process to the CUCM so the install process will not proceed any further.  I have tried downloading the ISO multiple times from the website but the same issue is still occurring.  If anybody has ran into this or has any suggestions or ideas on how to successfully upgrade, they would be greatly appreciated.  Thanks.

What's the exact ISO file you're trying to download??

You can also try to reach out to your SE or TAC so they can try publishing this for you.

The exact ISO file is UCSInstall_UCOS_11.5.1.11900-26.sgn.iso

If its an MD5 issue then you may try downloading on a different network setup as the image could be getting altered during download on current setup or request TAC to publish the image for you.
