Hi Ashish,
the rebalance is still running. It moved about 49.3 TB of 78 TB (estimated).
The initial amount of data saved on the s01, s02 and s03 servers was about 156TB, so I think that half of 156TB (78TB) should be moved to the new 3 servers (s04, s05 and s06).

In attachment you will find the outputs required.
Thank you,
