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.
