    • Decided that downgrade will not be supported until the 1.1.0 to 1.2.0 upgrade, during which users can downgrade to 1.1.0. This means this will not be a problem, since it only occurs downgrading to 1.0.0.

    Description

      When running downgrade tests for HDDS-4181, SCM failed to start when downgraded from 1.1.0 pre-finalized to 1.0.0. Log file is attached. It looks like HDDS-4496 introduced the incompatibility, and HDDS-4731 and HDDS-4851 (both applied when the test was run) provided some fixes, but not enough to support downgrades to 1.0.0.
