Description

We bulk moving regions to target RSGroup, and each movement of region will submit a TRSP, but one TRSP encounters exception will make the whole movement action terminate. Later regions will not be moved to correct servers unless reassign.

I think we can skip failed moved regions, and retry to move after all has been traversed.
