On a low load be BE2, migrate in a new replica RB, its action is copy a new replica; 3. chose any idle be BE3, use its replica RC as the copy source for replica RB in 2. for BE1 and BE2, their tag = T, their medium = M, and clusterStat.isMoreBalanced is just comparing their load. for BE3 as the copy source, its tag is unknown and no need to be T, it's just use as the copy source, it can be any BE.
