Moving a regular Site Property (not multi-tenant) did not successfully copy its value to the target module.
Further investigation seems to indicate that the logic is only checking if there is a tenant-specific value (using Site_Property) and only doing it for one tenant. This is definitely incorrect behaviour already for a multi-tenant scenario.
Worse is that it behaves this same way even when the site property is shared (as set via Site_Property_Definition.Is_Shared) where it should be using the shared value (using Site_Property_Shared). Instead it's not finding the Site Property (and writing it to the General log with a wrong source 'RoleMover' instead of 'SitePropertyMover' or 'ElementMover').
Is there anyone currently maintaining this component?
