Unable to move modifications to properties via update set or xml importDescriptionWhen modifications to some properties are captured into an update set but, when the update set is promoted to other environments customer updates to those properties will be missing from update set. One more scenario can be, Few properties cannot be updated via XML import/export.CauseThis is because, some of the properties are Private properties. you can search with filter 'Private is True' on sys_properties. XML import is restricted for these properties. It will not allow to create sys_update_xml record too for these records if it is not a manual modification on the same instance. So, when update set moved to another instance these sys_update_xml records will be missing. You may not see the error message on UI but, in transaction logs you can see "Skipping private property sys_properties_XXXXXX"ResolutionFor such properties we should only do manual updates on each instance.
