When I list keyspaces on my DSE cluster I get

myuser@cqlsh> DESC KEYSPACES;

dse_security  system       "OpsCenter"      system_traces  cfs
system_auth   cfs_archive  "HiveMetaStore"  XXXXXXXX       dse_system

where XXXXXXXX is our internal keyspace and the rest are essentially systems keyspaces. Which of the above can easily be recreated without a backup? AFAIK, neither What are best practices for backing up a cassandra cluster? nor Backing up and restoring data in Datastax documentation answers this.

Installing Opscenter will create the "OpsCenter" keyspace. Installing DSE will re-create the other system keyspaces. I think the only ks you need to worry about is your own user-defined keyspace. Don't forget to backup your schema, you will need that in order to do the restore.
