ServiceNow unable to revert an object to baseline during an upgrade - presented with an error When a hotfix was provided on a protected script for example look at the hotfix update set to check if the Replace on upgrade flag is set to true for that file in the update set? If it is set to false it can cause this issue. If it is false change the flag in the update set to true which should allow the file to be reverted to the baseline, release version. Just setting the flag in the already-applied update set seems to do the trick
