Redis [BUG] Segmentation fault error on importing data from old cluster

I have 3 existing Redis v4.0.2 nodes sharded by application (IBM Infosphere Streams DPS Toolkit). Now I have created a new v6.2.4 cluster and trying to import data from old nodes but keep on getting error Segmentation fault.

[root@strmrd01 bin]#  ./redis-cli --cluster import 10.162.53.247:7000 --cluster-from 10.162.53.248:6380 --cluster-replace --cluster-copy

I can't see anything in syslogs. Am I missing something? Please also share detailed docs of Redis-cli import, I couldn't it, in fact got command options from another issue

So redis-cli crashes.. Can you please run it under gdb and show a trace of the crash?
