From the way you wrote this, I suspect the name DC may have different
meaning here. Are you talking about the physical location (i.e server
rooms), or the Cassandra DC (i.e. group of nodes for replication purposes)?

Hello,
We have a Cassandra cluster deployed across three different data
centers, with each data center (DC1, DC2, and DC3) hosting 50
Cassandra nodes.
We are currently saving one replica in each data center.
We plan to migrate DC3, including storage and servers, to a new data
center.
1. What would be the best method to perform this migration, which
could take several days (2–5 days)?
2. Would relying on hints in the other two data centers be a good
approach?
Thanks
Edi
