      Description

      We have some opcode conflicts for edit logs between 0.20.20x (LV -19, -31) vs newer versions. For edit log loading, we dealt with this by forcing users to save namespace on an earlier version before upgrading. But, using a trunk OEV on an older version is useful since the OEV has had so many improvements. It would be nice to be able to specify a flag to the OEV to be able to run on older edit logs.
