After the migration when we monitoring on the cerebro the totals shards are not matching and data is growing twice .

Exactly double! Any chance the second graph is counting replicas as well whereas the previous one was simply counting only primaries?

You have way too many shards by the way.
Use _shrink to reduce that.
