 Description   

As part of the 3.8 upgrade/downgrade project, all upgrade/downgrade behavior that was specific to the transition between 3.4 and 3.6 should be removed. The storage team will oversee that all teams remove 3.4 to 3.6-specific upgrade/downgrade behavior in their respective projects. To facilitate this removal, the storage team would like each team to determine which upgrade/downgrade behavior is specific to the 3.4 to 3.6 transition and which is generic upgrade/downgrade behavior that should be preserved between releases. The storage team will update the generic upgrade/downgrade behavior locations to use the most up-to-date featureCompatibilityVersion values.
