Migrating DRUID to New Cluster

Hi community,

We have been using Druid from last year in production in a Region A Datacenter, now we have to move to Region B Datacenter. We are using HDFS (Running in replication 2TB Memory) as the storage along with DRUID running on a single large machine (32 CPU, 64 GB RAM).

What is the best way to migrate from the old datacetner to the new one. We are okay to give downtime to our customers. How do we migrate the data which is currently there on HDFS?

Any help/documentation on this would be really helpful.
