We want to migrate our ES cluster to use version 1.4.1 with doc_values.
We have 20 nodes with 4TB data.
What is the best practice? Can we just change the mapping and restart the
cluster?
How can we make sure the change was done?

Thanks for the answer.
What not clear to me is how to reindex such a change.
Restart is enough?
Can I use the backup-restore method?
Or do I need to scroll the data out and re-index after new mapping?
