    Description

      Currently in MigrationOptions in upgrade code the mmap option is only enabled if explicitly enabled.

      Given it provides much better migration speed it would be better to enable it by default (at least for non windows platforms) and provide a way to disable it by option. This would ensure that migration uses most suitable options per default
