I am trying to upgrade a UCM module from R10 to R11. I upload the iso through web manager solutions setting, i choose upgrade and it appears to go through the upgrade normal. i even get a message saying its been upgraded with no errors. However, the UCM reboots and when it comes back on it shows R1 as the version with R11 as the available upgrade. Why does it appear the upgrade is completing and upon reboot its back at R10?
