Description
In this section, http://docs.mongodb.org/manual/release-notes/2.8-upgrade/#upgrade-a-replica-set-to-2-8, we should mention that you can change the storage engine options to upgrade a replica set. We should be sure to mention that it will require a full-resync as the node comes back online.
Perhaps we should also suggest a 2-phase upgrade process where first one upgrades the binary and then in the second phase changes the storage engine in a rolling fashion.
