Hi Team,

I am trying to restore cluster in a different DC but DC names are being overwritten in new cluster with the original ones. I had to disable authentication and change DC names of all keyspaces. Can you please provide a solution.

Thanks in advance !!

Thanks, Hanumanth Prasad

Thanks for reporting the issue @HanumanthPrasad. There's definitely something we need to deal with regarding DC names.

Notes from planning:

This will probably only work with sstable loader. Without it, we restore schema direclty, and automating tweaking that would be way too ugly.
We should make Medusa fail early and clearly if the above is about to go down.
Also, we'll need to store information about which DC got backed up somewhere in the backup metadata (probably in the tokenmap).
