From Disney's Hollywood Studios Wiki
In reference to Studio Wiki, Retired refers to something that was in Disney's Hollywood Studios at one time, but no longer is. Several attractions have been "upgraded" rather than replaced or destroyed. Upgraded meaning that it keeps the central theme but is slightly different and goes under a different name.
