See this blog article for information on migrating to a new SAN or to new
disks in the same SAN:

Uh... yeah. So you do it during a maintenance period. If you do it by adding
the nodes and then evicting the old ones, your down time will be
considerably less than trying to migrate the databases to a new cluster.
However, I can see both sides of this one.
What I would do is:
1. Migrate my current cluster to the new disks
2. Add nodes and evict old nodes
However, an option would certainly be to:
1. Build a new cluster using the new disks
2. Migrate the databases to the new cluster
