Any beter way to do it?

2 node cluster windows 2008 r2 with node and file witness share
the cluster resource (DHCP) is on cluster disk F
now, we need to decommision the storage which holds file share and cluster disk.
We need to switch file share and cluster disk to new storage.
my plan is to take cluster disk offline and add new one. change the new one to F drive
and copy files from old disk to the new one.
then chanbge quorum from node and file witness share
the cluster resource to node majority; then change it to node and file witness share
(with new storage share)

Any beter way to do it?

Thank you!
